Abstract
The utility model provides a be applied to voussoir stopper of tractor, including brake chamber, expander, braking bottom plate, brake shoe, the technical core is: the expander is a two-way expander, the two-way expander is installed on the brake bottom plate, two adjusting sleeves of the two-way expander are respectively contacted with the other ends of the 2 brake shoes, return springs are arranged between the other ends of the 2 brake shoes, the brake air chamber is connected to an axle housing of the tractor during installation, a diaphragm of the brake air chamber is connected with a push rod of the two-way expander, the two adjusting sleeves of the two-way expander move outwards through wedge blocks on the push rod, and therefore the brake shoes are pushed to swing outwards. The utility model applies the wedge block brake to the tractor, when braking, the two sliding heads of the bidirectional expander move outwards under the action of the brake air chamber, and the brake shoe is forced to contact with the brake drum, thereby generating friction torque to decelerate or stop the vehicle; and simple structure, mechanical efficiency height, good reliability.
Description
Technical Field
The utility model relates to an automobile wedge block brake is especially being applied to the wedge block brake of tractor.
Background
At present, a brake of a tractor is a conventional drum brake, consists of a brake air chamber, a brake camshaft bracket, a brake adjusting arm, a brake bottom plate and a brake shoe assembly, and has the disadvantages of complex structure, heavy mass, low mechanical efficiency and poor braking reliability under overload or special conditions.
The wedge block brake is one kind of automobile drum brake and includes mainly brake air chamber, expander, brake bottom plate and brake shoe.
Disclosure of Invention
The utility model provides a be applied to the voussoir stopper of tractor, can guarantee braking effect, reduced the quality of stopper again and simplified the stopper structure, be convenient for pull arranging of axle to mechanical efficiency has been improved.
The technical scheme of the utility model is that: be applied to wedge block brake of tractor, including brake chamber, expander, soleplate, brake shoe, 2 brake shoes of symmetrical arrangement on soleplate, the brake shoe bush is installed to interference fit in soleplate's the mounting hole, and 2 brake shoes's one end is supported in the brake shoe bush through two shoes axle, its characterized in that: the expander is a two-way expander, the two-way expander is installed on the brake bottom plate, two adjusting sleeves of the two-way expander are respectively contacted with the other ends of the 2 brake shoes, return springs are arranged between the other ends of the 2 brake shoes, the brake air chamber is connected to an axle housing of the tractor during installation, a diaphragm of the brake air chamber is connected with a push rod of the two-way expander, the two adjusting sleeves of the two-way expander move outwards through wedge blocks on the push rod, and therefore the brake shoes are pushed to swing outwards.
The utility model has the advantages that: when the wedge block brake is applied to a tractor, the two sliding heads of the bidirectional expander move outwards under the action of a brake air chamber during braking, so that a brake shoe is forced to be in contact with a brake drum, and friction torque is generated to decelerate or stop the vehicle; and simple structure, mechanical efficiency height, good reliability.

Detailed Description
As shown in fig. 1 and fig. 2, the present invention is further described: a wedge block brake applied to a tractor comprises a brake air chamber 4, an expander 3, a brake bottom plate 1 and a brake shoe 2, 2 brake shoes 2 are symmetrically arranged on a brake bottom plate 1, brake shoe bushes 7 are arranged in mounting holes of the brake bottom plate in an interference fit manner, one ends of the 2 brake shoes 2 are supported in the brake shoe bushes 7 through two shoe sheet shafts 6, the expander 3 is a bidirectional expander which is arranged on the brake bottom plate 1, two adjusting sleeves of the bidirectional expander are respectively contacted with the other ends of the 2 brake shoes 2, a return spring 5 is arranged between the other ends of the 2 brake shoes, a brake air chamber 4 is connected on an axle housing of the tractor during installation, a diaphragm of the brake air chamber 4 is connected with a push rod of the bidirectional expander, the two adjusting sleeves of the bidirectional expander move outwards through the wedge blocks on the push rods, so that the brake shoes are pushed to swing outwards.
For those skilled in the art, simple combination, equivalent replacement, and further improvement without departing from the technical concept of the present invention shall be included in the protection scope of the present invention.
