Abstract
The utility model discloses a connecting structure for the chassis and the real wheels of an agricultural vehicle. The connecting structure comprises a chassis, rear wheels, an axle shaft and a half case, wherein one end of the half case is fixed on the chassis, and a brake drum and a rear axle flange are mounted at the other end of the half case, one end of the axle shaft is connected with the gear on the chassis, the other end of the axle shaft is connected with a rear axle flange, the rear axle flange and a brake bush are connected and mounted through a screw, the brake bush is fixed on the rear axle flange, and the rear wheel is mounted on the brake bush. One end of the axle shaft is connected with the gear in a matched manner through a rectangular spline, the other end of the axle shaft is connected in a matched manner with the rear axle flange through an involute spline; the half case is equipped with two centripetal force bearings, and the axle shaft is fixed through the two centripetal force bearings. The brake bush is fixed on the rear axle flange through two tapered roller bearings. According to the connecting structure for the chassis and the real wheels of the agricultural vehicle, by designing and mounting the structure of the axle shaft and the half casing, the wheel span of the rear wheels are widened effectively, so that the entire vehicle width is increased, and an entire vehicle is enabled to be more stable and safer in driving.
Description
Technical field
The utility model relates to the chassis structure of a kind of farm machinery, particularly a kind of farm vehicle.
Background technology
Farm vehicle occupies very consequence in China's rural area transportation market, can be used for farmland operation when the busy farming season, also can be used for short-distance transport, is one of important transportation instrument of Rural Areas at Present.But farm vehicle exists the shortcoming of safety deficiency in the time that mountain region road conditions are poor in the time of hauling operation, such as the stability of braking safe is not high, the stationarity deficiency of driving process.On farm vehicle market, conventional chassis is 91 chassis, and through use development for many years, 91 chassis are comparatively ripe technically, and stability is relatively good.But the wheelspan on 91 chassis itself is narrower on the one hand, causes car load width little, in driving process, comparatively jolts, and steady not, safety is not high; The brake system of 91 chassis configuration itself is gear brake on the other hand, gear brake can seriously reduce the service life of gear, and safety factor is not high, have larger potential safety hazard for the larger road conditions of the mountain region gradient, and 91 chassis cannot directly be installed brake drum and are transformed into drum brakes.
Summary of the invention
The purpose of this utility model is to provide a kind of farm vehicle chassis and trailing wheel connection structure, widens original wheelspan, brake drum is installed, to promote vehicle security energy.
For achieving the above object, this farm vehicle chassis and trailing wheel connection structure, is characterized in that: comprise chassis, trailing wheel, semiaxis and half shell, described half shell one end is fixed on chassis, and the other end is provided with brake drum and back axle flange; Described semiaxis one end is connected with the gear being arranged on chassis, and the other end is connected with the prominent unit of back axle, and the prominent unit of described back axle is by screw rod and the connection of brake sleeve pipe, and brake sleeve pipe is fixed on back axle flange, and described trailing wheel is arranged on brake sleeve pipe.
Described semiaxis one end is connected by rectangular spline and gear, and the other end is connected by invoice serration and the prominent unit of back axle.
Described half shell is provided with two centripetal force bearings, and semiaxis is fixed by these two centripetal force bearings.
Described brake sleeve pipe is fixed on back axle flange by two tapered roller bearings.
Substantive distinguishing features of the present utility model and progress are:
This farm vehicle chassis and trailing wheel bindiny mechanism, by semiaxis of design and installation and half-shell structure, effectively widen the wheelspan of trailing wheel, to widen car load width, makes the car load more steady safety of travelling; And can be by the different designs of semiaxis and half shell size and attachment face, installing brake drum with being connected of trailing wheel, realize the drum brakes of farm vehicle, effectively promote braking performance of vehicle.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of this farm vehicle chassis and trailing wheel connection structure.
Component serial number and title in figure:
Half shell 1, chassis 2, trailing wheel 3, semiaxis 4, the prominent unit 5 of back axle, brake sleeve pipe 6, back axle flange 7, brake drum 8, gear 9, centripetal force bearing 10, tapered roller bearing 11.
The specific embodiment
Below in conjunction with accompanying drawing, structure of the present utility model is described.
Shown in Fig. 1, this farm vehicle chassis and trailing wheel connection structure, comprise chassis 2, trailing wheel 3, semiaxis 4 and half shell 1, and described half shell 1 one end is fixed on chassis 2, and the other end is provided with brake drum 8 and back axle flange 7.Described semiaxis 4 one end are connected with the gear 9 being arranged on chassis 2, and the other end is connected with the prominent unit 5 of back axle, and the prominent unit 5 of described back axle is by screw rod and 6 connections of brake sleeve pipe, and brake sleeve pipe 6 is fixed on back axle flange 7, and described trailing wheel 3 is arranged on brake sleeve pipe 6.
Semiaxis 4 one end are connected by rectangular spline and gear 9, and the other end is connected by invoice serration and the prominent unit 5 of back axle.
Half shell 1 is provided with two centripetal force bearings 10, and semiaxis 4 is fixed by these two centripetal force bearings 10.
Brake sleeve pipe 6 is fixed on back axle flange 7 by two tapered roller bearings 11.
The principle of work of this farm vehicle chassis and trailing wheel connection structure is described below in conjunction with accompanying drawing:
Chassis 2 power are delivered to semiaxis 4 by gear 9, semiaxis 4 is connected by invoice serration with the prominent unit 5 of back axle, so the prominent unit 5 of back axle can be along with semiaxis 4 is equal to rotation, because the prominent unit 5 of brake sleeve pipe 6 and back axle passes through together with screw rod connection, can be synchronized with the movement, and trailing wheel 3 is arranged on brake sleeve pipe 6, final chassis 2 transmission of power directions are: the prominent unit 5 → brake of gear 9 → semiaxis 4 → back axle sleeve pipe 6 → trailing wheel 3, realize the synchronized rotation of trailing wheel 3 and gear 9.
