Title A certain type of parking brake lever design
Abstract
The parking brake system on the vehicle chassis is a very important mission-critical systems. For conventional mechanical handbrake, the handbrake lever is one of the components most commonly used by drivers. In order to reduce the space occupied by the joystick while motorists more effort, this design is proposed and designed to have a cable structure variable hand brake lever device ratio. By reference to a section of the parameters of light cars were parking the car performance and brake lever tension calculations to determine the scope of the change lever ratio. Design uses a structure around the sheave grooves to achieve the leverage ratio and thus change the elliptical shape parameters of the parking brake lever length of each part was OK. Finally, the use of SolidWorks and AutoCAD design complete the relevant assembly drawing and figure drawing working parts, while its intensity examination and checking travel joystick.
Keywords： parking brake lever ; cable structure; variable leverage ratio; intensity examination; check of the travel joystick
