Abstract
A wheeled tractor brake system adopting a caliper disc brake structure comprises a brake mechanism and a braking maneuver control mechanism and is characterized in that the brake mechanism comprises a caliper disc brake as well as a half shaft and sleeve assembly that are matched; and a brake maneuver system comprises a pneumatic control oil maneuver mechanism. Through design improvement on the brake system, a brake disc is arranged on a hub seat and the caliper disc brake is arranged on the half shaft and the sleeve. As the installation position of the brake moves outwards, the impact on the half shaft by brake moment is reduced when braking, the service life of the half shaft is prolonged and the brake is convenient for repair. The mechanism adopts the pneumatic control oil maneuver mechanism for braking maneuver and the brake system adopts an air brake to aid in braking. The brake system provides power through a diesel engine and uses the air pressure offered by an air compressor to control a brake master pump, thus achieving the braking effect. The mechanism adopts the air brake to aid the system, thus not only being capable of reducing the labor intensity of manual maneuver and but also improving the response sensitivity in braking time.
Description
Technical field
The utility model relates to a kind of brake system structure of trac., specially refers to no posture wheel-tire tractor brake system.
Background technology
At present, no posture wheel-tire tractor brake system all adopts shoe brake or complete disc brake, and maneuvering system adopts complete human control; But along with trac. operation pattern and the diversified development of outfitting tool, behind trac. and other machine coordination, progressively develop to the mechanical engineering direction, this just needs the trac. brake system will satisfy the new feature of frequently braking when running at high speed; Should guarantee that running brake is having stable brake efficiency under the frequent operation condition continuously, the labour intensity of the human control that causes in the time of also frequently braking will being reduced simultaneously, the traveling comfort of raising brake operation.
The utility model content
At the problem of above-mentioned existence, the purpose of this utility model is to provide a kind of stop mechanism of using at no posture wheel-tire tractor.For achieving the above object, the stop mechanism that the utility model trac. is used comprises: caliper disk brake that stop mechanism is selected for use and the semiaxis that matches and cover pipe assembly etc., braking control system adopts gas control oil steering unit.
A kind of wheel-tire tractor brake system that adopts the caliper disk brake structure, described brake system comprises stop mechanism and brake operation control mechanism, it is characterized by: described stop mechanism comprises: caliper disk brake and the semiaxis that matches and cover pipe assembly; Braking control system comprises gas control oil steering unit.
Further, described brake system specifically comprises: air compressor 1, storage tank 2, air brake valve 8, booster pump 7, caliper disk brake 5 and brake disc 4; It is characterized by: brake disc 4 is arranged on the hub seat 3, and caliper disk brake is arranged on semiaxis and the cover pipe assembly 6.
Further, adopt the gas auxiliary braking of stopping; Provide power by diesel engine, the air pressure that utilizes air compressor to provide is controlled booster pump.
The beneficial effects of the utility model are:
1, by design improvement, brake disc is installed on the hub seat, caliper disk brake is installed on the axle tube brake system.Owing to move outside the drg installation site, glancing impact reduces the impact of lock torque to semiaxis, prolong the semiaxis period of service, and brake service is convenient.
2, this mechanism brake operation adopts gas control oil steering unit, and brake system adopts the gas auxiliary braking of stopping.Provide power by diesel engine, the air pressure that utilizes air compressor to provide is controlled booster pump, thereby reaches braking effect.This mechanism adopts gas ancillary system of stopping, and not only can reduce the labour intensity of human control, and can improve the sensitieness of braking time reaction.
Description of drawings
Be described in further details this use is novel below in conjunction with accompanying drawing and enforcement.
Fig. 1 is a gas control oil caliper disc brake system fundamental diagram of the present utility model.
Fig. 2 is a structural representation of the present utility model.
The specific embodiment
Gas control oil caliper disc braking control system principle of work of the present utility model:
As shown in Figure 1, 2, braking control system of the present utility model comprises: air compressor 1, storage tank 2, air brake valve 8, booster pump 7, caliper disk brake 5.Brake disc 4 is arranged on the hub seat 3, caliper disk brake 5 is installed on semiaxis and the cover pipe assembly 6, and is positioned at steel Figure 12.Owing to move outside the drg installation site, glancing impact reduces the impact of lock torque to being arranged on the semiaxis on the tractor chassis 11 and overlapping pipe assembly 6, prolong the semiaxis period of service, and brake service is convenient.When the needs glancing impact: the air brake valve pedal is pressed down with the foot down, and booster pump changes pneumatic mode into hydrostatic drive, and the piston that promotes caliper disk brake moves.When the needs brake off, loosen the air brake valve pedal, the pressurized air of booster pump 7 ejects from the air brake valve deflation hole, and the piston of caliper disk brake 5 is got back to virgin state.
As shown in Figure 2, need glancing impact, air brake valve 8 is arranged on that stretcher 9 presses down with the foot down on the trac. floor 10, at this moment, pressure is that the pressurized air of 0.44-0.7Mpa enters in the booster pump 7, and booster pump changes pneumatic mode into the hydrostatic drive pattern, and the piston and the friction lining that promote caliper disk brake 5 compress brake disc 4, thereby brake wheel reaches braking effect.During the brake off state, loosen the pedal 9 of air brake valve 8, the pressurized air in the booster pump 7 is discharged from the deflation hole of air brake valve 8, and piston in the caliper disk brake 5 and friction lining are removed brake disc 4 is compressed, thereby removes the braking mode of trac..
