The present invention relates to an arrangement (1) for assisting a parking brake (10), which parking brake (10) comprises a brake lever (12) which is supported in a carrier device (14) such that it is pivotable between a release position and a locking position and is able to be coupled to a braking system by means of a transmission means. The arrangement (1) comprises a lifting element (20) with an energy storage unit (22), which is operatively connected to the brake lever (12). The operative connection comprises a redirecting element (30) which is supported in a way pivotable about a pivot axis (32) and is arranged in such a way that the redirecting element couples the lifting element (20) to the brake lever (12).

A planetary gear assembly, in particular for an electromechanical service or parking brake for a motor vehicle. The planetary gear assembly can include a central sun gear, a plurality of planetary gears rotatably mounted on a planetary carrier, and a ring gear enclosing the planetary gears. The planetary gears can be mounted by the planetary carrier, such that the planetary gears roll off both the sun gear and the ring gear, whereby the sun gear, the planetary carrier or the ring gear is non-rotatably held by a holding unit with a holding torque. A force-sensing device can be arranged between the holding unit and the non-rotatably held element, or between the holding unit and an intermediate component non-rotatably connected to the held component. The force-sensing device can measure the force acting between the held component and the holding unit as a result of the holding torque.

A control module, which is mounted on a handlebar of a bicycle, includes a base, a grip, a control bar, and a bolt. The base has a hole, and the hole has a first section and a second section, wherein the second section is bigger than the first section. The base is fitted to the handlebar whereby a sidewall of the first section touches the handlebar. The grip is fitted to the handlebar, and has a portion received in the second section of the hole of the base. The control bar is provided on the base to control a brake module or a derailleur module. The bolt is provided on the base, wherein both the base and the grip are fixed to the handlebar at the same time by tightening the bolt.

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.

Described herein are various embodiments of trolleys usable for traversing cables such as zip lines. Various embodiments have been particularly adapted to perform better under different circumstances or in different applications using braking including impact braking.

A machine includes a prime mover having a power take-off, a chassis configured to support at least an operator and the prime mover, a subframe pivotally coupled to the chassis about a pivot axis at a first location, at least one drive device configured to drive wheels of the machine, a drive belt and pulley arrangement. The subframe is further coupled to the chassis via at least one suspension device at a second location. The at least one drive device is driven by the prime mover and is coupled to the subframe. The pulley arrangement is configured to direct the drive belt from the power take-off of the prime mover to at least one drive pulley on the at least one drive device. The pulley arrangement comprises an idler pulley having a diameter and a rotational axis. The idler pulley is coupled to the chassis such that the rotational axis is spaced from the pivot axis by no greater than 1.5 times the diameter.

An emergency controller includes an emergency stop switch to be activated upon detection of an emergency, a control section to be enabled upon activation of the emergency stop switch, and an emergency stop mechanism configured to execute and release braking by a brake mechanism under control of the control section. The control section is configured to perform execution control for causing the emergency stop mechanism to execute braking by the brake mechanism and for stopping operation of the engine upon the condition that the emergency stop switch is activated while the engine is in operation. The control section is configured to perform restoration control for causing the emergency stop mechanism to release the braking by the brake mechanism upon the condition that the emergency stop switch is deactivated and the engine is started.

A cable-driving arrangement of a vehicle includes a cable main body and a sheath. The cable main body is composed of a plurality of unit filaments, and distal ends of the unit filaments are melted to be integral to form a melted end. The cable main body is for being relatively positionably disposed on a vehicle with a portion near the melted end. The sheath is sleeved around the melted end.

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.
