Abstract
The utility model discloses a rear axle for light vehicles, which is composed of a rear axle housing assembly, a main speed reducer assembly, a differential mechanism assembly, a half axle, a braking drum band wheel hub assembly, and a brake assembly. The utility model is characterized in that the brake of the rear axle is a brake by utilizing the air pressure to drive a cam to open through expansion, an air chamber assembly whose push rod is hinged with an adjusting arm assembly is arranged on the rear axle housing assembly, and the adjusting arm assembly is engaged with the braking cam of the brake assembly by a spline. The utility model has the advantages of reliable and stable braking, large braking force, labor-saving operation, simple structure, convenient manufacture and maintenance, etc. and provides reliable safety guard for the speed increase and the load-bearing capacity of the complete vehicle.
Description
It is Biodge device behind the lilliput car below 3 tons that the utility model relates to a kind of automobile axle device, particularly load carrying ability.
Current domestic all load carrying abilities are 3 tons and all adopt the hydraulic drive type drg with Biodge device behind the lilliput car of subordinate, though it is simple in structure, air application time is short, but it has the following disadvantages: during low temperature, the braking liquid flowing power in the brake fluid pressure driving device is poor; May gasify again during high temperature, produce vapour lock; Invade or fluid seepage situation if any air, brake efficiency will reduce even be entirely ineffective, and its braking force not as the air pressure drive-type greatly, these shortcomings all will limit the speed of development of present transit industry.
The purpose of this utility model is to be the deficiency in the lilliput car drg below 3 tonnes at above-mentioned existing load-carrying, and Biodge device behind a kind of lilliput car that proposes, it has, and braking force is big, and braking is reliable, handles characteristics such as laborsaving.
The purpose of this utility model is achieved in that it is made up of rear axle housing assembly, main gearbox assembly, differential assembly, semiaxis, brake wheel belt wheel hub assembly, brake assembly.Main gearbox assembly is connected with rear axle housing assembly mutually by bolt, differential assembly then links to each other with the ring gear of main gearbox assembly by bolt, semiaxis is meshed with differential assembly by spline, the flexible bearing of crossing is connected with rear axle housing assembly in the brake wheel belt wheel hub assembly, the outside links to each other with semiaxis with bolt, and brake assembly is connected on the casing flange dish of rear axle housing assembly by bolt.Its gordian technique is that drg is an air pressure power cam spreading formula drg, it is that the air chamber assembly is housed on rear axle housing assembly, the push rod of air chamber assembly becomes to be hinged with adjusting arm assembly, adjusting arm assembly is meshed with the brake shoe expander of brake assembly by spline, brake shoe expander one end is packed in the Cam rest, and the other end is packed in the air chamber support.
Below in conjunction with drawings and Examples the utility model is described in detail.
Fig. 1 is the utility model constructional drawing;
Fig. 2 is Figure 1B-B cutaway view;
Fig. 3 is the utility model brake assembly figure;
Fig. 4 is Fig. 3 A-A cutaway view;
Fig. 5 is for existing domestic load carrying ability is that the hydraulic pressure that automobile adopted below 3 tonnes drives formula brake assembly figure.
Referring to accompanying drawing, the utility model is made up of rear axle housing assembly 5, main gearbox assembly 1, differential assembly 3, semiaxis 10, brake wheel belt wheel hub assembly 11, brake assembly 7.Main gearbox assembly 1 is connected with rear axle housing assembly 5 mutually by bolt 4,3 of differential assemblies link to each other with the ring gear 2 of main gearbox assembly 1 by bolt, semiaxis 10 is meshed with differential assembly 3 by spline, the flexible bearing 8,9 of crossing is connected with rear axle housing assembly 5 in the brake wheel belt wheel hub assembly 11, the outside links to each other with semiaxis 10 with bolt, and brake assembly 7 is connected on the casing flange dish of rear axle housing assembly 5 by bolt 6.Drg is an air pressure power cam spreading formula drg, air chamber assembly 15 is housed on rear axle housing assembly 5, the push rod 23 and the adjusting arm assembly of air chamber assembly 15 are hinged for 14 one-tenth, adjusting arm assembly 14 is meshed with the brake shoe expander 12 of brake assembly 7 by spline, brake shoe expander 12 1 ends are packed into and are fixed in the Cam rest 22 on the brake support plate 18, and the other end is packed in the air chamber support 13.Referring to Fig. 3, brake shoe assembly 17 lower ends of drg are hinged for 18 one-tenth with the brake support plate assembly with brake shoe brake cheek bobbin 20 by shoe plate axle connecting panel 19, shoe plate shaft locking sheet 21.Brake shoe assembly 17 upper ends abut against on the brake shoe expander 12 by the pulling force of spring 16.When automobile needs glancing impact under steam, enter in the air chamber assembly 15 from the gas in the pneumatic actuator, it is overhanging to promote push rod 23, driving adjusting arm assembly 14 rotates, thereby brake shoe expander 12 is rotated thereupon, the moving shoe plate axle 20 of brake shoe assembly 17 coilings is outwards rotated, be close to brake wheel belt wheel hub assembly 11, lean on friction between them to make car deceleration or stop.And that hydraulic drive type drg shown in Figure 5 is the piston 24 that promotes in the brake cylinder 25 by the fluid of hydraulic actuator is overhanging, thereby promotes brake strap assembly 17 outer commentaries on classics, produces friction with brake wheel belt wheel hub assembly 11 and brakes.
The utility model has following good effect and advantage: because the utility model has adopted the air pressure driving Cam spreading formula brake, thus overcome the phenomenons such as vapour lock of former hydraulic pressure drive-type brake, so it Brake reliable and stablely, and it is big to have brake force, handles the advantages such as laborsaving, for the bearing capacity of car load and The raising of speed provides reliable safety guarantee. This brake structural is simple, is convenient to make and maintenance.
