Abstract
The invention discloses a high-performance brake device. The brake device comprises a brake cylinder, a rocker arm connecting rod, a brake drum and a brake power component, wherein the brake power component is arranged on the inner side of the brake drum and comprises a cam, a fixed seat and slide block components; the cam is arranged in a position close to the middle of the fixed seat; the two ends of the rocker arm connecting rod are respectively arranged on the cam and the brake cylinder; the slide block components are arranged around the cam; each slide block component comprises a slide block, a brake block, a fixed arm and a return spring; the slide block is arranged on the fixed seat; the brake block is arranged at the end of the slide block, which is close to the brake drum; the fixed arm is arranged on the fixed seat; and the return spring is arranged between the slide block and the fixed arm. The high-performance brake device disclosed by the invention enables the brake block and the brake drum to perform friction brake through the coordination of the cam and the slide block; since the pressure and the friction force between contact surfaces increase with load, the brake performance is improved, the abrasion is reduced and local thermal deformation of the brake drum is avoided; and furthermore, roller wheels can be arranged on raised parts to prevent the cam from abrading, so that the service life is increased.
Description
Technical field
The present invention relates to a kind of brake gear, particularly a kind of simple in structure, deceleration and stopping performance is high, the High Performance brake gear of long service life.
Background technology
Two traditional hoof brake structures only have two brake facings, in when brake, brake facing and brake drum the wipe contact area less than 40%, therefore very easily produce brake facing and skid, generate heat and cause brake drum local heating to be out of shape, brake efficiency is low, even can cause accident such as brake inefficacy etc.
Summary of the invention
Technical matters at above-mentioned existence the objective of the invention is: proposed a kind of simple in structure, deceleration and stopping performance is high, the High Performance brake gear of long service life.
Technical solution of the present invention is achieved in that a kind of High Performance brake gear, comprises wheel cylinder, rocker-arm link, brake drum, brake Power Component; Described brake Power Component is arranged on the inboard of brake drum; Described brake Power Component comprises cam, permanent seat, slide block assembly; Described cam is arranged on pivotally near on the position in the middle part of the permanent seat; The two ends of described rocker-arm link are separately positioned on cam and the wheel cylinder; Described slide block assembly has a plurality of, a plurality of slide block assemblies be arranged on cam around; Described each slide block assembly all comprises slide block, brake facing, fixed arm and pull back spring; Described slide block is slidably disposed on the permanent seat; Described brake facing is arranged on the end of slide block near brake drum; Described fixed arm is arranged on the permanent seat; Described pull back spring is arranged between slide block and the fixed arm; Described cam is provided with a plurality of lug bosses; The number of described lug boss is no less than the number of slide block assembly.
Preferably, each brake facing makes all brake facings be combined into a complete circumference approx all along the circumferential extension of brake drum.
Preferably, described slide block assembly has four.
Preferably, described lug boss has four.
Preferably, be provided with rotating roller on described each lug boss.
Because the utilization of technique scheme, the present invention compared with prior art has following advantage:
High Performance brake gear of the present invention withstands a plurality of slide blocks by cam, and slide block drives brake facing and brake drum friction braking, and the pressure of the contact surface of brake facing and brake drum and friction force can increase with the increase of load, therefore, skidding can not occur; And the area of contact of brake facing and brake drum is big, has improved deceleration and stopping performance, reduces wearing and tearing, has avoided local heating's distortion of brake drum; And on the lug boss wearing and tearing that roller is avoided cam can be set, thereby improve service life.
Description of drawings
Below in conjunction with accompanying drawing technical solution of the present invention is described further:
Accompanying drawing 1 is the structural representation of a kind of High Performance brake gear of the present invention;
