Abstract
A modified disc-braked automobile front axle consists of a 140 type automobile front axle body, a front hub assembly and a disc brake assembly, wherein the 140 type automobile front axle body consists of an I-beam, a knuckle, a transverse tie rod assembly, a transverse tie rod arm and a drag link arm in connection. A brake caliper of the disc brake is connected with the knuckle of the front axle body, a brake disc is connected with the front hub assembly, and the mounting position of a gas inlet chamber is modified to be adaptable to the connection position of the disc brake. The modified disc-braked automobile front axle evidently improves shortages of large surface deformation of a brake friction plate, unstable braking efficacy, larger size, larger mass, difficult realization of automatic adjustment of brake clearance, and more difficult maintenance existing in an original 140 type drum-braked automobile front axle, and increases comprehensive performance of the original 140 type drum-braked automobile front axle.
Description
Technical field
The utility model relates to a kind of improved type disc type brake automobile front axle, belongs to automobile component manufacturing technology field.
Background technology
The heavy motor vehicle propons is general to adopt non-independent hanging integral to forge H-girder, the drum brake mechanism structure, in actual use, the drum brake mechanism braking force is relatively poor, the brake wheel running surface is that arc surface easily deforms, the brake efficiency instability, brake efficiency reduces morely behind the brake friction Face Immersion, must could recover brake efficiency through braking twice or more.Under the identical situation of output lock torque, the size and the quality of drum brake mechanism are bigger, the difficult automatic compensation of realizing brake clearance.If will have drum brake mechanism in the medium and heavy automobile front axle now is adapted as plate disc brake and can obviously improves above-mentioned weak point.
The utility model content
The purpose of this utility model is exactly: a kind of improved type disc type brake automobile front axle is provided, and 140 type disc type brake automobile front axles particularly are to improve the deceleration and stopping performance of this medium and heavy goods carrying vehicle.
Improved type disc type brake automobile front axle described in the utility model, form by 140 type automobile front axle pontics, front wheel hub assembly and brake assembly, the propons pontic is connected to form by H-girder, steering swivel, tie rod assembly, spindle arm, vertical pulling lever arm, described brake assembly is a disk brake assembly, described brake disk is connected with the front wheel hub assembly, brake clamp is connected with steering swivel on the propons pontic by the gusset piece set up, and improves the air chamber installation site and the plate disc brake connection location adapts.
The utility model has following advantage than the drum brake propons before improving:
1), the plate disc brake running surface is the plane, is difficult for taking place moderate finite deformation, brake efficiency is stable;
2), immersion back usefulness reduces lessly, and need only can recover normal through twice braking;
3), export under the identical situation of lock torque the size of drg and fair less;
4), Heat stability is good, brake disc has only radial expansion, and is minimum along the thermal expansion amount of thickness direction, do not influence braking;
5), be easier to realize automatic play compensation, other maintenance operation is also easier.
The utility model can improve obviously that the brake bush areal deformation that former drum brake automobile front axle exists is big, brake efficiency is unstable, oad is big, quality is big in a word, the brake clearance automatic compensation is difficult realizes and shortcoming that maintenance is difficult.Improved this product overall performance.
Description of drawings
Fig. 1 is the utility model structural representation;
Fig. 2 is a gusset piece structural representation in the utility model;
Fig. 3 is the utility model air chamber and drg connection location figure.
Among the figure: bolt, 3-air chamber, 4-wheel hub, 6-gusset piece, 7-plate disc brake, 8-steering swivel, 9-that 1-connects brake disk and wheel hub connect the bolt and nut of bolt, 10-spindle arm, 11-connection plate disc brake and the steering swivel of spindle arm and steering swivel, bolt and nut, 13-vertical pulling lever arm, 14-H-girder, the 15-tie rod assembly that 12-connects vertical pulling lever arm and steering swivel.
The specific embodiment
As shown in Figure 1, improved type disc type brake automobile front axle described in the utility model is made up of front wheel hub 4 assemblies, disk brake assembly 7,140 type automobile front axle pontics, described 140 type automobile front axle pontics are made up of by bolted connection H-girder 14, steering swivel 8, tie rod assembly 15, spindle arm 10, vertical pulling lever arm 13, the brake clamp of plate disc brake 7 assemblies is connected with preceding pontic steering swivel 8 by the gusset piece 6 usefulness bolt and nuts of setting up 11, and the brake disc of plate disc brake 7 assemblies is connected by bolt 1 with the front wheel hub assembly that size adapts to.
For adapting to the requirement of repacking plate disc brake, change air chamber 3 installation sites into drg the place ahead (being the automotive operation direction) level upwards 0～90 ° by former drg top; Described gusset piece is provided with plate disc brake connecting bore and steering swivel connecting bore, and wherein connecting drg fore-and-aft direction screw pitch-row is 104～114, and the above-below direction pitch-row is 124～134, and aperture size is φ 15～φ 20.In addition this propons front wheel hub assembly is relevant with steering swivel is of a size of: wheel rim distribution circle 270～280, front wheel hub seam 210～218,7 °～9 ° at steering swivel inclination angle, steering swivel dress kingpin bore aperture 33～41, the seam diameter 128～138 of drg is installed, charge of oil seal diameter phi 95～φ 105, steering swivel neck bearing retaining diameter dimension is φ 50～φ 60, steering swivel outer bearing retaining diameter dimension is φ 35～φ 45.Dimensional units is mm.
Through above-mentioned improvement, the disc type brake drum is connected with 140 type pontics, thereby becomes improved type disc type brake automobile front axle.This improved type automobile front axle proves that by road examination and stand test Combination property improves greatly, and product obtains medium-to-high grade user's favor.
