Abstract

The utility model relates to a tractor loader, which belongs to automobile field; a whole car is mainly composed of a dynamic force assembly, the assembly of a machine frame, a braking assembly, an assembly for speed changing, etc. The structure of the tractor loader is characterized in that a machine frame is provided with a structure of a complete frame, which is formed by a crossbeam, a supporting frame and a sommer by welding; besides, damping devices such as a hanging spring device, a leaf spring, etc. are respectively arranged between the machine frame and a gearbox and on a front bridge and on a rear bridge. The utility model has the advantages of proper length of the whole car, good damping performance, flexible operation and rotation, stabilization and safty.

Description

Full frame load-carrying trac.

The utility model relates to a kind of full frame load-carrying trac., belongs to automotive field, particularly trac..

The constructional feature of existing compact tractor is: complete machine is divided into dilatory office and loading space front and back two parts, connect with towing pin between the front and back, thereby the complete machine size is long partially, does not have shock absorption device simultaneously, has increased the driving difficulty to chaufeur, has also aggravated degree of fatigue.

For these reasons, the purpose of this utility model is to provide to people the full frame load-carrying trac. of a kind of full posture, band shock absorption device.

Above-mentioned purpose of the present utility model is achieved in that and adopts full posture rack construction, thereby shortened car load length, and the damping leaf spring is installed below frame, make the car load running steadily, drive comfortable, particularly significantly improve hill climbing ability, adopted gearbox body to hang spring structure in addition, improved the service life of gearbox body balancing sleeve.

Description of drawings:

Fig. 1 is an integral structure lateral plan of the present utility model;

Fig. 2 is rack construction figure of the present utility model;

Fig. 3 hangs spring structure figure for gearbox body of the present utility model.

Below in conjunction with accompanying drawing the utility model is elaborated:

Accompanying drawing is depicted as a kind of enforcement of the present utility model, it is mainly by frame, dynamic assembly, the direction assembly, the clutch assembly, brake assembly, speed changing assembly, the electrical equipment assembly, the hydraulic pressure assembly and before, back axle assembly constitutes, its mid frame [1] is by bumper/spoiler front cross rail [2], after cross member [3], powered support [4], a cylinder bracket [5] and a left side, right crossbeam [6], [7] the full shelf structure that is welded, and on a frame left side, right crossbeam [6], [7] be fixed with four groups of eight hangers on, four groups is respectively left front two hangers [8], [9], right front two hangers [10], [11], a left side latter two hanger [12], [13], right latter two hanger [14], [15], one group of leaf spring is housed between every group two hangers, four groups of leaf springs [16], [17], [18], [19] being positioned at two anterior its stage casings of frame [1] in is connected with propons [20] respectively, two its stage casings at rear portion are connected with back axle [21] respectively, be equipped with one between cylinder bracket [5] and the change speed gear box [22] and hang spring arrangement [23], this hangs spring arrangement is by screw rod [24], spring [25], pressure spring plate [26], nut [31] is formed, wherein two screw heads are stuck in respectively in two through holes [28] on the cylinder bracket [5], two screw rods [24] pass two through holes [29] on the pressure spring plate [26] respectively, be with a spring [25] on two screw rods [24] respectively, spring [25] one ends are pressed on the pressure spring plate [26], the other end is pressed on the pad [30], nut [31] is screwed in screw rod end holddown spring [25], and pressure spring plate [26] is horizontally fixed on the change speed gear box [22].Can be during use according to the difference of load carrying ability, adjustment nut [31] is to appropriate predetermincd tension, but the bridge wheelbase is generally 2050mm according to driving engine and load-carrying difference also appropriate change wheelbase in addition, and its scope is between 1950～2200mm.

The utility model has the advantage of: car load length is suitable, goes slick, and can overcome because of belt transmission back axle The problem of being out of shape after the load-carrying, strengthen damping device make Vehicle Driving Cycle steadily, safety.
