Description
Technical field
The utility model relates to a kind of vehicle and lowers speed or halt and the device of double as braking during standstill, and particularly a kind of drg that is installed on the vehicle rear bridge input shaft end especially stops to the deceleration of vehicle and to play the device of auxiliary braking effect.
Background technology
Drg is equipped with at two trailing wheel places of vehicle rear bridge both sides, and the deceleration of self-propelled vehicle or sudden stop all can be realized by these two drgs of driver's operation.The problem that exists is at present: the drg quality of indivedual manufacturers does not guarantee that braking force is not enough sometimes.Be too economic pursuit benefit of some car owner more in addition, the overload of vehicle phenomenon often takes place, cause vehicle to need the glancing impact braking force not enough.When overload of vehicle was tending towards the descending situation again, car brake pressure especially increased especially.The friction lining of mechanical brake can damage even burn, and the safety traffic accident takes place easily.And friction lining damages or when burning, repairs very difficult.The brake system position of especially agricultural three-wheeled motor vehicle is narrow, and the automobile repair department of specialty often is reluctant to repair.
Be to increase braking force, the frictional area that people's desire increases friction lining or brake wheel comes remedying, but is subjected to space condition restriction such as tyre rim and is difficult for solving.In addition, can cause the vehicle frame distortion during overload of vehicle, cause oil pipe or gas-tpe fitting relative position to move, leakage of oil or gas leakage can appear in brake system, cause brake system failure at last.For this reason, people have to consider how to manage to improve the brake system of self-propelled vehicle for guaranteeing traffic safety
Summary of the invention
The purpose of the utility model is to remedy above-mentioned deficiency, provides a kind of simple in structure, with low cost to society, and car brakeing power is increased, and braking effect is better, thus the vehicle rear axle of vehicle and personal safety can guarantee emergency situation the time.
The technical solution of the utility model is achieved in that
The back axle of band brake on a kind of input shaft comprises: left and right rear wheel brake, the left and right half of connection diff in the rear axle housing body, rear axle housing body, diff and back axle input shaft; It is characterized in that: described back axle input shaft is provided with brake equipment.
Described brake equipment comprises: install the drg on the back axle input shaft, insert in the bevel housing bolt of rear end plate that drg is installed on the described rear axle housing body.
Drg on the described back axle input shaft comprises: medium pore be contained in the described back axle input shaft and be fixed in back-plate on the rear axle housing body, and back-plate fastens and and brake wheel, back-plate and the brake wheel of the spline fitted of back axle input shaft head between brake shoe brake cheek and brake-shoe return spring.
The technical measures of further optimizing the technical program are:
Be covered with well-regulated equally spaced many radiating gills that have mutually on the circle wall of described brake wheel.
The side of described brake wheel is provided with Thermal packer, and of described Thermal packer is connected with the sidewall of brake wheel, and the other end is connected with the transmission shaft of self-propelled vehicle.
The one side of described Thermal packer is fixed on the sidewall of brake wheel, and another side is provided with the connecting bore of motor vehicle transmission axle, is instlated tubulars that combine together with two sides between two sides, establishes a plurality of louvres on the instlated tubular.
The advantage of the utility model is:
Because the back axle input shaft is provided with brake equipment, makes the vehicle rear axle diff have brake action concurrently.The brake equipment that is provided with on the back axle input shaft is the complemental brake system of the original brake equipment of vehicle, and it is simple in structure, and is with low cost, but makes the car brakeing better effects if, thus the safety of vehicle and the person can guarantee emergency situation the time.

The specific embodiment
Each parts Reference numeral title is described as follows:
Left rear wheel drg 1, rear axle housing body 2, left half axle 3, diff 4, right axle shaft 5, off hind wheel drg 6, back axle input shaft 7, torque arm 8, back-plate 9, brake-shoe return spring 10, brake wheel 11, Thermal packer 12, instlated tubular 121, louvre 122, connecting bore 123, brake shoe brake cheek 13, bolt of rear end plate 14, bevel housing 15, radiating gill 16.
Below in conjunction with accompanying drawing the utility model is described in further detail.
The back axle of band brake on a kind of input shaft comprises: left and right rear wheel brake 1,6, the left and right half 3,5 of connection diff in the rear axle housing body 2, rear axle housing body, diff 4 and back axle input shaft 7; It is characterized in that: described back axle input shaft 7 is provided with brake equipment.
Described brake equipment comprises:
Install the drg on back axle input shaft 7, insert in the bevel housing 15 bolt of rear end plate 14 that drg is installed on the described rear axle housing body 2.
Drg on the described back axle input shaft 7 comprises: medium pore be contained in the described back axle input shaft and be fixed in back-plate 9 on the rear axle housing body, and back-plate 9 fastens and and brake wheel 11, back-plate and the brake wheel of the spline fitted of back axle input shaft head between brake shoe brake cheek 13 and brake-shoe return spring 10.
The technical measures of further optimizing the technical program are:
Be covered with well-regulated equally spaced many radiating gills 16 that have mutually on the circle wall of described brake wheel 11.The drg glancing impact, brake shoe brake cheek 13 heatings, the temperature of brake wheel 11 raises simultaneously, 16 of radiating gills that are located on brake wheel 11 circle wall have certain intervals, not only enlarge the area of contact of brake wheel 11 and air, and be convenient to air and between radiating gill, circulate, distributed more heat.
The side of described brake wheel 11 is provided with Thermal packer 12, and a sidewall with brake wheel 11 of described Thermal packer is connected, and the other end is connected with the transmission shaft of self-propelled vehicle.
The one side of described Thermal packer 12 is fixed on the sidewall of brake wheel 11, and another side is provided with the connecting bore 123 of motor vehicle transmission axle, is instlated tubulars 121 that combine together with two sides between two sides, establishes a plurality of louvres 122 on the instlated tubular.Connect vehicular transmission shaft with Thermal packer, the one, vehicular transmission shaft and heat-producing brake wheel 11 are separated, the 2nd, the louvre 122 on Thermal packer instlated tubular 121 and the instlated tubular 121 distributes a large amount of heats, avoids the transmission shaft heating.
When chaufeur spurs the mechanical arm of drg on the diff, affected torque arm 8, torque arm 8 is opened brake shoe brake cheek 13, friction lining on the brake shoe brake cheek 13 withstands on brake wheel 11 inwalls, and friction force stops back-plate 9 rotations, and then back axle input shaft 7 is stopped the rotation, finally keeping within bounds two trailing wheels rotates. like this, the drg of drg on the diff on vehicle rear wheel implemented braking to vehicle, is convenient to finish the car brakeing task, guarantees vehicle braked safety.
The torque arm of the utility model embodiment belongs to mechanical braking, can certainly replace with oil pressure or air pressure, but oil, air pressure still belongs to technical scope of the present utility model.
