Abstract

The utility model relates to a multipurpose engineering power driven chassis. With the utilization of an improved rear end face of the transmission box body of a tractor, the utility model can directly carry out the series connection and the power driving with an engine through a clutch assembly. The front end of the transmission box body is connected with a hinge bracket to form larger space in the front end of the driven chassis. Additionally, the utility model is provided with a preset power driving shaft and a differential lock device, which can is very favorable to hinge with various work devices to form variant mechanical products of different sorts and types. The utility model has the advantages of reasonable structural configuration of overall design and strong universal interchangeability. The multipurpose engineering power driven chassis is a universal power matching driven chassis in fields of high road, municipal engineering, building, gardening, environmental protection, etc.

Description

Multipurpose engineering power drven chassis

It is a kind of many with engineering power driven chassis that the utility model provides, and it is the general mating power machinery that is applicable to machineries such as highway, building, municipal administration, gardening.

At present, engineering goods such as small-sized tip lorry, axle type loader, small vibrating formula roller, deicing machine, mower, except that small-sized tip lorry finalized the design produce, all the other substantially still belong to the prepattern product, spcific power drives the chassis owing to select for use separately, causes model various, and single, the general interchangeability of performance is poor, be unfavorable for specialized High-efficient Production, limited the development of the said goods.The present invention is directed to the existing small four-wheel tractor of China, its structure can not be used for or satisfy the shortcoming of the requirement of the various distortion engineering goods of exploitation, existing small four-wheel tractor overall structure is rearranged, engine position is in improved transmission case body rear end, increase defeated moving axis of preposition power and differential locking-device device in the transmission case body, the transmission case body front end is established hinge bracket, be beneficial to directly be connected into all kinds of modification engineering goods with various equipments, it is single to have solved former small four-wheel tractor performance preferably, disadvantages such as comprehensive economy difference.

The utility model purpose provides a kind of many with engineering power driven chassis, it has preposition power take-off shaft, engine position is in the transmission case body rear end, front end is provided with hinge bracket, general layout design is reasonable, easy and various equipment directly is articulated and connected and forms various special-purpose machinery products, has changed the in-use performance and the field of application of former small four-wheel tractor.

The utility model is described in further detail below in conjunction with accompanying drawing.

Fig. 1 is the utility model overall construction drawing and and the hinged low loader engineering goods that connect composition of a kind of equipment (in the frame of broken lines).

Fig. 2 is the utility model transmission front view.

Fig. 3 is that the M-M main gear launches birds-eye view.

1 is that equipment (diagram is that working device of loader also can be other equipments such as tip lorry) is articulated and connected on hinge bracket 2 in the accompanying drawing, transmission case body 3 front end fixed connecting pieces 2, part 3 aft end faces directly are connected in series through clutch assembly 4 and driving engine 5, carry out power driven, power-transfer clutch 7 and coupler 8 drive power input shaft 9 runnings in the engine crankshaft 5 seam parts 4, part 9 right-hand members are fixedly connected driving gear 10 through the following driven gear 13 of intermediate gear 11 drives, part 11 utilizes bearing fixing to be supported on the flanged shaft 12, and part 12 is fixedly connected on transmission gearbox shell 17 rear box walls.Part 13 is supported on the preposition power take-off shaft 15 by bearing fixing, shift sleeve 14 can mesh with female splines on the part 13 on the part 15, part 15 from differential gear box 22 lower surfaces by and support the location by F, A bearing the part 17 forward and backward tank walls, be fixedly connected on part 9 drive bevel gear 16 through bevel gear shaft 18 and on the I shaft gear 19 that is fixedly connected, finish I-VI level transmission process, I-VI level transmission belongs to former small four-wheel tractor structure substantially, and its transmission principle omits.Part 9 connects journal stirrup C centre bearer D below the muscle by part 17 casing front and rear wall centre bearer E, B and casing middle part and supports the location.Part 18 is supported to locate by part 17 journal stirrup G centre bearer H and tank wall centre bearer J.The transmission of VI level, it is terminal transmission, form by diff 20, time semiaxis 21, last semiaxis 25, bearing K outer ring is fixed in the part 17 terminal driving holes, inner ring is fixed on differential cover 23 axle journals, and the axle journal endoporus has the mesh key tooth and separates by the engagement of shift sleeve 24 on the control piece 25 and part 23 axle journal internal key teeth and finish each mode of operation of differential locking-device.

The utility model front end is provided with hinge bracket, and engine position is in the transmission gearbox rear end, and it is rationally distributed to have a compact conformation, and general interchangeability is good, can finely satisfy and be beneficial to exploitation kind of distortion engineering goods.
