Embodiment Construction

[0007] The structure and use of the present invention will be described in detail below in conjunction with the embodiments given in the accompanying drawings. Refer to attached figure 1 Or 2, this kind of dump truck direct-connected oil pump has a pump body (1) and a pump cover (2) matched with it and the gear shaft (7) of the transmission gear, which is characterized in that the input end of the gear shaft (7) The sleeve is connected with a spline sleeve (8) with a spline (9), and the pump cover is extended to be able to close the connection between the gear shaft and the spline sleeve, and can be reasonably connected with the installation end of the power take-off of the original dump truck. The sealing ring (3) between the gear shaft and the pump cover is fixed and positioned by the retaining ring (4), and there is a spacer (10) at the part where the gear shaft (7) is connected with the spline sleeve, and the pump cover (2) There is an oil drain observation hole (11) betw...

Abstract

The invention discloses a directly-connected oil pump for a dump truck. The directly-connected oil pump is provided with a pump body, a pump cover and a gear shaft of a transmission gear, wherein the pump cover is matched with the pump body; a spline sleeve with a spline is sleeved and connected to the input end of the gear shaft; the pump cover is prolonged to a connecting part which can be used for enclosing the gear shaft and the spline sleeve; a sealing ring between the gear shaft and the pump cover is fixed and positioned through a retainer ring; an isolation pad is arranged at a position where the gear shaft and the spline sleeve are sleeved and connected; and an oil leakage observing hole is formed between the pump cover and the gear shaft. The invention has the advantages: a gear oil pump is directly connected with a power takeoff device through the spline, so that the weight is lowered, the energy consumption is lowered, the transmission efficiency is increased, the structure is simple, and the cost is reduced effectively in comparison to the conventional transmission mode; moreover, a sealing isolation pad is arranged between the spline and the gear shaft; and meanwhile, the pump cover is provided with the oil leakage observing hole, so that the problem of leakage of the gear oil pump into a transmission case at the power takeoff end caused by the sealing problem is solved effectively.

Description

technical field [0001] The invention belongs to a gear oil pump for automobiles, in particular to a direct-connected oil pump for a dump truck. Background technique [0002] At present, the gear oil pump used on the dump truck is fixed by the pump frame, and there is a transmission shaft in the middle to connect the oil pump and the power take-off. This transmission method has low efficiency, takes up a lot of space, is expensive, and has a high failure rate. In order to overcome the above-mentioned problems that the dump truck gear pump exists, the designer of the present invention has done serious research and proposed the purpose of the invention of the present invention. Contents of the invention [0003] The purpose of the invention is to overcome the disadvantages of low efficiency, large space occupation, high cost and high failure rate of the current gear oil pump used on dump trucks. That is, a direct-connected oil pump for a dump truck is provided. [0004] The...
