Abstract

A small-sized chassis is a mini four-wheel drive automobile chassis, comprising an engine, a speed changer, a front transmission shaft, a back transmission shaft, a front axle, a back axle, a front suspension, a back suspension, wheels and a vehicle frame. The front output end and the back output end of the speed changer output power synchronously to the front axle and the back axle, and the structure of the speed changer and a transfer case adopted by a traditional non-AWD is replaced. The front axle adopts a main reducer, the separation and the combination of which are controlled by electricity. A four-wheel drive switch in a cab controls the separation and the combination of the front axle in order to realize the conversion of four-wheel drive and two-wheel drive. The back axle adopts a limited-slip differential which can prevent the unilateral wheel from slipping and improve the passing ability of the vehicle. The utility model absorbs the advantage of a common miniature wagon and increases the four-wheel drive function; the realization of the four-wheel drive function omits the conventional transfer case; and the utility model has the advantages of simple and reliable structure and good passing ability, which is applicable to field running.

Description

The compact car chassis

Technical field

The utility model relates to a kind of mid-get car chassis, belongs to International Classification of Patents B60T1/00 " braking element " technical field.

Background technology

At present, minitruck generally adopts two to drive pattern, and is more abominable on some road surfaces, the area that needs minitruck again, the needs that have minitruck employing 4 wheel driven, but because the arrangement space of minitruck is little, traditional change-speed box adds difficult enforcement of 4 wheel driven structure of part-time case.

Summary of the invention

Car chassis described in the utility model comprises parts such as driving engine, change-speed box, front and back transmission shaft, front and back bridge, fore suspension and rear suspension, wheel, and driving engine and change-speed box connect to ground by the blob of viscose that suspends.Synchronous outputting power does not have traditional part-time case before and after the change-speed box, and change-speed box passes to the propons main reduction gear to the power of propons output by front propeller shaft, passes through the left and right driving semiaxis again, and transmission of power is arrived front driving wheel.Change-speed box passes to rear-end gear reduction to the power of back axle output by rear propeller shaft, and rear-end gear reduction arrives rear drive sprocket by left and right half with transmission of power again.Utilize the electrical controller in the propons main reduction gear to carry out the conversion that 4 wheel driven and two drives.The propons main reduction gear links to each other with front axle body assembly by bolt, and front axle body assembly links to each other with vehicle frame by four bolts.

Front propeller shaft adopts an end slip formula, and rear propeller shaft adopts telescoping.

Back axle adopts rigid drive axle, equipped Limited slip differential.

Propons adopts broken drive bridge.

Vehicle frame has the structure that the front and back draw gear is installed.

The fuel tank of fuel-feed system is arranged in the below at vehicle frame rear portion.

Preceding main reduction gear is connected on the body assembly of front axle.

Car chassis of the present utility model adopts full synchronized gear transmission, and synchronous outputting power is given forward and backward bridge before and after the control comfort, change-speed box, thereby has cancelled part-time case, makes structure compact more.Change-speed box is provided with 2 Ultra-Low Speed shelves, the demand of vehicle power in the time of can better satisfying abominable road surface.MacPherson type independent front suspension, automatically controlled 4 wheel driven, rack and pinion steering gear are integrated on this novel chassis, and vehicle performance is better brought into play.Employing has the propons of front axle body assembly, and installation and maintenance are convenient, increased vehicle frame rigidity.The MacPherson type independent front suspension has reduced nonspring carried mass, has alleviated because of the impact of pavement roughness vibrational load to automobile, and vehicle running smoothness is good.The propons main reduction gear adopts magnetic clutch, clutch freely, reliable operation, when the combination of needs propons, when entering the 4 wheel driven state, as long as press the 4 wheel driven switch onboard, preceding bevel housing is casting aluminium material and structure, and is in light weight, compact conformation.Back axle is equipped with three circular pitch anti-skid final drives, can effectively prevent one-sided tyre skidding, improves the crossing ability of vehicle.Steering system adopts rack and pinion steering gear, and compact conformation is in light weight, handles light.Adopt special-purpose mud ground tire, driving adherence properties and good stability are highly suitable for the field and travel.

Description of drawings

Fig. 1 is the birds-eye view of the utility model car chassis.

Fig. 2 is the front view of car chassis.

Among the figure: 1, engine assembly, 2, transmission assembly, 3, front propeller shaft assy., 4, rear propeller shaft assy., 5, propons, 6, back axle assembly, 7, front suspension, 8, rear suspension, 9, wheel, 10, frame assembly, 11, rack and pinion steering gear assembly, 12, front axle body assembly, 13, preceding main gearbox assembly, 14, tank assembly

The specific embodiment

Referring to Fig. 1, Fig. 2, driving engine 1 and change-speed box 2 are connected with vehicle frame 10 by rubber mounting, export synchronously change-speed box 2 front and back, preceding output is connected with front propeller shaft 3 by spline, the flange connection of the other end of front propeller shaft 3 and propons main reduction gear 13, the flange of mouth is linked to each other with rear propeller shaft 12 by bolt behind the change-speed box, the flange connection of the rear end of rear propeller shaft 4 and back axle 6.

The power that driving engine 1 sends reaches change-speed box 2 through power-transfer clutch, output synchronously before and after the change-speed box, pass to back axle 6 through rear propeller shaft 4 backward, pass to propons main reduction gear 13 through front propeller shaft 3 forward, when in operator's compartment, pressing the 4 wheel driven switch, preceding main reduction gear energising combination, propons enters mode of operation, and vehicle is in the 4 wheel driven pattern; When pressing the 4 wheel driven switch once more, the outage of preceding main reduction gear separates, the propons state of deactivating, and vehicle is in two and drives pattern;

The enforcement pattern of other associated components of chassis is as follows:

The propons pattern is a broken drive bridge; The back axle pattern is a rigid drive axle; The deflector position is that put on a left side, and the steering system pattern is a rack and pinion steering gear; Engine location is mid-; The service brake pattern is the wheel edge trig; The front suspension pattern is a MacPherson strut; Rear suspension pattern-asymmetric steel spring, double adjustable shock absorber; The transmission shaft pattern is an open type, telescoping.
