The brake device has the advantages of simple structure, small mass, good heat radiation, reliable performance and good ride, and can effectively prevent medium-sized and heavy-duty trucks from running off and insufficient brake force in the braking process so as to improve the running security of medium-sized and heavy-duty trucks.
Description
Technical field
The utility model relates to a kind of brake device for car, particularly a kind of medium and heavy brake device for car that uses plate disc brake.
Background technology
The brake assembly of domestic present medium and heavy goods carrying vehicle all adopts drum brake mechanism, and drum brake mechanism is divided into internal expanding drum brake and external beam type drum brake mechanism again.The fixed friction element of internal expanding drum brake is a pair of brake shoe brake cheek that has the shoe plate that rubs, and is installed on the back-plate, and back-plate then is anchored on the flange of front-axle beam or rear-axle casing; Its spin friction friction element utilizes the inside face of the satisfactory post of brake wheel and the outside face of brake shoe lining to produce friction moment as a pair of friction surface, so be called shoe brake again for being fixed on the wheel hub.The fixed friction element of external beam type drum brake mechanism is to have friction lining and the less brake collar of rigidity; Its spin friction element is a brake wheel, and the inner arc surface that utilizes the outer cylinder surface of brake wheel and brake collar friction lining is as a pair of friction surface, produce friction moment and act on brake wheel, so be called external contracting drum brake again, external contracting drum brake seldom adopts on automobile, so internal expanding drum brake abbreviates the formula drg of plucking up one's courage usually as, and usually said drum brake mechanism promptly is meant this interior type drum-type structure of opening.The rotating element of plate disc brake is a vertical installation and is the brake disc of driving surface with two sides that its fixed friction element generally is the slipper that is positioned at the brake disc both sides and has friction lining.When brake disc was clamped by the slipper of both sides, friction surface just produced the friction moment of doing on the brake disc.This drg is commonly used for the car side brake of car, also can be used as the centre brake of various automobiles.
The utility model content
The purpose of this utility model provides a kind of medium and heavy autotruck brake equipment that uses plate disc brake, improves medium and heavy automobile brake stability and reliability.
Described medium and heavy goods carrying vehicle brake equipment, comprise front wheel hub assembly, propons and brake assembly, described propons is front axle band steering swivel and tie rod assembly, described drg is the jaw type plate disc brake that floats, this disk brake assembly is connected with front axle band knuckle assembly and front wheel hub assembly by fastener, wherein the brake caliper assembly of plate disc brake is connected with front axle steering knuckle, and brake disc is connected with Hub assembly.
The front-axle steering joint and the tie rod assembly of described brake equipment comprise front axle, vertical pulling lever arm, spindle arm and steering swivel, front axle wherein adopts and forges the H-girder pattern, the vertical pulling lever arm is contained in steering swivel upper end, the left and right sides by cone washer, spring washer and bolt of rear end plate, left and right sides spindle arm is contained in steering swivel lower end, the left and right sides by fastener, and steering swivel is contained on the front axle with tie rod assembly by stub, bearing cap shim, damping thrust bearing.
The medium and heavy goods carrying vehicle brake equipment of the utility model with existing its beneficial effect of drum brake system comparison is:
1, better heat stability;
2, water stability is better;
3, insensitivity is good;
4, lock torque and automobile move forward and backward travel irrelevant;
5, under the condition of the onesize lock torque of output, the quality and the size of plate disc brake are littler than drum brake mechanism;
6, lining pad easier replacing after wearing and tearing, structure is also simpler, and maintenance is easily.
7, little (0.05～0.15mm), this has just shortened the operating time of oil cylinder piston, and makes the force transmission ratio of braking drive organ that the possibility of increase be arranged the brake disc of plate disc brake and the gap between lining pad;
8, the het expansion of brake disk can not cause the brake-pedal travel loss as braking drum-type system drg brake wheel, and the design of the automatic engagement positions in gap can be simplified;
9, plate disc brake is easy to constitute the multi-circuit braking drive system, makes system that reliability and safety preferably be arranged, to guarantee automobile each wheel uniformity ground gradual braking under any speed of a motor vehicle;
10, can conveniently realize the brake wear warning, so that in time change lining pad.
