An electric parking brake device 10 includes an actuator 16 capable of operating and releasing the center brake 6, a power transmission cable 17 connected to the actuator 16, and a manual operation portion 21. The actuator 16 includes an electric motor, and the center brake 6 of the vehicle 1 can be operated or released by a driving force of the electric motor. The manual operation portion 21 is an operation portion for manually operating the actuator 16 without using the driving force of the electric motor in an emergency or the like when the electric motor stops working. An arrangement position of the manual operation portion 21 is a position that is exposed to the wheel house, and is covered from an outer side in a vehicle width direction by the front wheel 11 in a state where the front wheel is oriented in a straight direction.

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 child transport carrier includes a handle bar and a rotatable brake actuator disposed along a lengthwise axis of the handle bar. A first cable having a first end and a second end is coupled to the rotatable brake actuator. A first wheel brake of a first wheel is coupled to the first end of the first cable. Rotating the rotatable brake actuator around the lengthwise axis of the handle bar activates the first wheel brake.

This invention relates to a hydraulic brake device with a time difference, which utilizes an innovative brake structure to realize the time difference braking technique in which the rear wheel preferentially activates the braking action, to prevent the vehicles from slipping or spillover. Moreover, said time difference hydraulic brake device in the present invention can increase the braking force of the front wheel brake, this allows bicycles, motorcycles, electric scooters, automobiles and other vehicles to effectively improve braking performance and safety.

An electromechanical actuator is provided comprising a housing, a rotor disposed in the housing, an selective gearbox mechanically coupled to the rotor and disposed in the housing, a first output of the selective gearbox configured to rotate at a different speed than the rotor, and a second output of the selective gearbox configured to rotate at a same speed as the rotor.

A stroller including a pair of wheels and a cross bar extending therebetween. A pedal is coupled to the cross bar, and is transitional relative thereto between locked and unlocked configurations. A pair of braking pins is operatively coupled to the pedal. Each braking pin is transitional relative to a corresponding wheel between locked and unlocked configurations. Each braking pin is engaged with the corresponding wheel when the braking pin is in the locked configuration, and each braking pin is disengaged with the corresponding wheel when in the unlocked configuration. The braking pins are coupled to the pedal such that movement of the pedal from the unlocked configuration to the locked configuration causes the braking pins to transition to their respective locked configurations, and movement of the pedal from the locked configuration to the unlocked configuration causes the braking pins to transition to their respective unlocked configurations.

A shift and brake lever assembly including a brake lever having a first surface facing a handlebar and a second surface facing away from a handlebar. A shift lever may be mounted to the second surface of the brake lever using mounting components. Complementary apertures of the various mounting components may lie on a common longitudinal axis.
