Abstract
The utility model discloses an electric car front axle double-brake device which comprises a front axle beam, a steering knuckle, a brake disc and brakes, wherein the front axle beam is composed of a steel frame and connected with the steering knuckle, steering knuckle pins are arranged in the connecting position between the front axle beam and the steering knuckle, the brake disc is connected with the steering knuckle, a front axle hub is arranged in the connecting position between the brake disc and the steering knuckle, the brakes are installed on the two sides of the brake disc, and a friction plate is arranged in each brake. When the electric car front axle double-brake device is used, the two brakes which are symmetrically installed are fixedly installed on the front axle hub. Each friction plate and the friction surface of the brake disc are adjusted to abut against each other and an abutting gap between each friction plate and the friction of the brake disc is adjusted, so that the brakes are started. A movable clamp of each brake moves, and each friction plate tightly abuts against the friction surface of the brake disc. The movable clamp of each brake conducts returns. Each friction plate releases the friction surface of the brake disc. Therefore, the brake circulation of a front axle is completed. The electric car front axle double-brake device has the advantages of being simple in structure, fast in heat dissipation, light in weight, convenient to adjust, particularly good in heat resistance when the load of an electric car is heavy, and stable in braking effect.
Description
Technical field
The utility model relates to the two brake equipments of a kind of Frong bridge of electric vehicle.
Background technology
In modern elec. vehicle was made, propons was main components, and the braking ability of propons is the key index of vehicle.It is drum brake mechanism that at present Frong bridge of electric vehicle braking is continued to use, and drum brake mechanism is owing to being the inner sealing structure, and heat dispersion is poor, can assemble a large amount of heats in braking procedure.Very complicated distortion easily occurs in brake strap and wheel hub under temperatures involved, easily produce fading of brake and the phenomenon that flutters, and causes the decline of propons deceleration and stopping performance, is difficult to adapt to the competition requirement of produce market.
Summary of the invention
The technical problems to be solved in the utility model provides a kind of simple in structure, and rapid heat dissipation is lightweight, and is easy to adjust.Particularly resistance to elevated temperatures is good during high capacity, the two brake equipments of Frong bridge of electric vehicle that braking effect is stable.
For addressing the above problem, the utility model adopts following technical scheme: the two brake equipments of a kind of Frong bridge of electric vehicle of the present utility model, comprise axle beam, steering swivel, brake disc and drg, described axle beam is that a steelframe consists of, described axle beam links to each other with steering swivel, described axle beam and steering swivel junction are provided with knuckle pivot pin, described brake disc links to each other with steering swivel, described brake disc and steering swivel junction are provided with the propons wheel hub, described drg is installed in the both sides of brake disc, be provided with friction lining in the described drg, one end face of described steering swivel is middle indent, it is provided with circular hole in two planes up and down, and an end of described axle beam is bumped into the middle indent position of steering swivel, and described steering swivel other end is provided with bearing.
As technical scheme preferably, described brake disc adopts the mode of welding to captive joint with the propons wheel hub.
As technical scheme preferably, described knuckle pivot pin penetrates the steering swivel circular hole corresponding with axle beam, is actively coupled with axle beam.
As technical scheme preferably, described bearing and propons wheel hub are actively coupled.
As technical scheme preferably, described drg is provided with more than two groups.
As technical scheme preferably, described friction lining is for can regulate friction lining.
The beneficial effect of the two brake equipments of a kind of Frong bridge of electric vehicle of the utility model is: offsets and pushes against the gap by regulating friction lining and brake disc friction face, and the startup drg, the adjustable cramp of drg moves, and friction lining pushes against the friction face of brake disc; The adjustable cramp backhaul of drg, the friction face of friction lining take-off the brake dish has been finished the braking working cycle of propons.
Description of drawings
In order to be easy to explanation, the utility model is done to describe in detail by following specific embodiment and accompanying drawing.
Fig. 1 is the structural representation of the two brake equipments of a kind of Frong bridge of electric vehicle of the utility model;

The specific embodiment
Consult illustrated in figures 1 and 2, the two brake equipments of a kind of Frong bridge of electric vehicle, comprise axle beam 1, steering swivel 2, brake disc 4 and drg 5, described axle beam 1 is that a steelframe consists of, described axle beam 1 links to each other with steering swivel 2, described axle beam 1 is provided with knuckle pivot pin 6 with steering swivel 2 junctions, described brake disc 4 links to each other with steering swivel 2, described brake disc 4 is provided with propons wheel hub 7 with steering swivel 2 junctions, described drg 5 is installed in the both sides of brake disc 4, be provided with friction lining 8 in the described drg 5, one end face of described steering swivel 2 is middle indent, it is provided with circular hole in two planes up and down, and an end of described axle beam 1 is bumped into the middle indent position of steering swivel 2, and described steering swivel 2 other ends are provided with bearing 3.
Described brake disc 4 adopts the mode of welding to captive joint with propons wheel hub 7.
Described knuckle pivot pin 6 penetrates circular hole corresponding to steering swivel 2 and axle beam 1, is actively coupled with axle beam 1.
Described bearing 3 is actively coupled with propons wheel hub 7.
Described drg 5 is provided with more than two groups, and in this enforcement example, described drg 5 is provided with two groups.
Described friction lining 8 is for can regulate friction lining.
The two brake equipments of a kind of Frong bridge of electric vehicle of the utility model have the following advantages: during use, two groups of symmetrical drgs of installing are fixedly installed in the propons wheel hub, offset and push against the gap by regulating friction lining and brake disc friction face, start drg, the adjustable cramp of drg moves, and friction lining pushes against the friction face of brake disc; The adjustable cramp backhaul of drg, the friction face of friction lining take-off the brake dish has been finished the braking working cycle of propons.It is simple in structure, and rapid heat dissipation is lightweight, and is easy to adjust.Particularly resistance to elevated temperatures is good during high capacity, and braking effect is stable.
The above only be the specific embodiment of the present utility model, but protection domain of the present utility model is not limited to this, and any variation or replacement of expecting without creative work all should be encompassed within the protection domain of the present utility model.Therefore, protection domain of the present utility model should be as the criterion with the protection domain that claims were limited.
