A tire engaging brake for use with a vehicle having a vehicle frame supporting a tire from a suspension includes a base securable to the vehicle frame, a brake pad mounting arm pivotally connected to the base, and a brake pad connected to the brake pad mounting arm. An over-center linkage has an inner link pivotally connected at an inner end to the base at a position spaced from the pivotal connection of the brake pad mounting arm to the base. An outer link of the over-center linkage is pivotally connected at an inner end to the inner link and is pivotally connected at an outer end to the brake pad mounting arm. A lever arm is cooperable with the inner link for pivoting the inner link, the outer link and the brake pad mounting arm between a retracted position and a tire engaging position in which the inner link and the outer link extend in an over-center condition.

An electric bicycle charger assembly includes a trailer that can be attached to a seat post of an electric bicycle thereby facilitating the electric bicycle to tow the trailer. A pair of wheels is each of the wheels is rotatably attached to the trailer and a pair of charging units is each integrated into a respective one of the wheels generate electricity when the trailer is being towed. Each of the charging units is electrically coupled to the electric bicycle for charging the electric bicycle. A braking system is integrated into the trailer and the braking system is in communication with a braking apparatus of the electric bicycle thereby assisting with slowing and stopping.

Systems and methods for emergency brake systems are provided herein. In this regard, a brake system may comprise a summing lever having a first end and a second end, a brake handle coupled to the first end of the summing lever, the brake handle rotatably coupled about a first axis, and a linear actuator having a plunger, the plunger being coupled to the second end of the summing lever. In various embodiments, an idler link may be coupled between the brake handle and the first end of the summing lever. The brake system may further comprise a brake cable coupled between the summing lever and a brake metering valve. The brake metering valve may be actuated in response to at least one of the brake handle being rotated about the first axis or the linear actuator being actuated.

A brake mechanism is provided, including: a main body, for connecting to a vehicle, having a penetrating hole for a wire to dispose therethrough, the wire having an insertion end which is smaller than the penetrating hole in radial dimension; a handle, restrictably pivoted to the main body via a pivot portion, having an assembling portion; the insertion end being directly axially penetrable through the penetrating hole to be fixedly connected to the assembling portion.

A braking device for a vehicle such as, for example, a walking frame, a stroller or a disabled wheelchair, includes: a hand grip extending along an extension axis X-X adapted to be rotatably mounted on a handlebar of a vehicle; a slide operatively connected to the cable of a vehicle brake; the slide being translatable between a locked position tensioning the cable of a brake and an unlocked position leaving loose the cable of a brake, and vice versa; and at least one pin element integral with the hand grip and engaged with a profile of the slide; the pin element sliding with respect to the profile between a first position, in which the slide is in the unlocked position, and a second position, in which the slide is in the locked position, and vice versa.

A trolley for traversing a zip line includes a first load-bearing sheave rotatably mounted to one or more side plates, and a second load-bearing sheave rotatably mounted to the one or more side plates and rearward of the first sheave. The trolley also includes an anchor point on the trolley for attaching a payload. When the trolley decelerates, forces acting on the payload create a downward load on the first sheave and the second sheave.

A safety structure for a hand brake contains: a casing, a body, a roller rotatably, a first brake line, a second brake line, and a third brake line. The first brake line are connected with a first brake and a second brake of a vehicle, and the second brake line is coupled with a first controller on a left handle of the vehicle, the third brake line is coupled with a second controller on a right handle of the vehicle. The first brake line is bent in half and has two shoulders adjacent to the roller, and an outer diameter of each of the two shoulders is more than the first brake line so that when the first brake line is broken, at least one of the two shoulders stops inside the body or the casing, and at least one of the first and second brakes stops the vehicle.

A brake piston includes a piston pocket. The piston pocket receives a nut that is axially moveable along a center axis. The nut is restricted from rotating within the piston pocket when a torque due to a frictional engagement between a nut seal and an inner pocket wall, one or more projections, or both is greater than an it torque at the nut. The nut is rotatable within the piston pocket when a torque due to the frictional engagement between the nut seal and the inner pocket wall, the one or more projections or both is less than the input torque at the nut and is less than the torque due to the frictional engagement between the piston and the piston seal.

A vehicle steering system includes a steer detection apparatus configured to detect a steered position of a steer wheel assembly relative to a steer axle. The steered position corresponds to a direction of turn of a vehicle. A brake actuator is configured to actuate a braking system of the vehicle, and the braking system is configured to brake a first drive wheel assembly independently from a second drive wheel assembly mounted to a drive axle. The first drive wheel assembly is located on a side of the vehicle corresponding to the direction of turn. The system further includes a linkage assembly operatively coupling the steer detection apparatus to the brake actuator. In response to the steered position detected by the steer detection apparatus, the brake actuator actuates the braking system to brake the first drive wheel assembly.

An example assembly comprises: a brake shaft comprising gear teeth formed on a circumferential portion of the brake shaft, wherein the brake shaft is substantially constrained from moving in a longitudinal direction along a longitudinal axis of the brake shaft; and a brake gear that is rotatably coupled to a drive shaft of a motor, wherein the brake shaft is rotatable about the longitudinal axis between (i) a first position at which the gear teeth of the brake shaft are disengaged from the brake gear, thereby allowing the brake gear and the drive shaft to rotate, and (ii) a second position at which the gear teeth of the brake shaft engage the brake gear, thereby precluding the brake gear and the drive shaft from rotating due to the brake shaft being constrained from moving in the longitudinal direction.
