Detailed Description

In order to make those skilled in the art better understand the technical solution of the present invention, the technical solution in the embodiment of the present invention will be clearly and completely described below with reference to the drawings in the embodiment of the present invention, and it is obvious that the described embodiment is only a part of the embodiment of the present invention, and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

As shown in fig. 1-4, a vehicle comprises a chassis of a frame, a gearbox is arranged on the frame, an output shaft of the gearbox is connected with a power takeoff 9, and the power takeoff 9 is connected with an oil pump 2 through a transmission shaft 4. Universal joints are arranged at two ends of the transmission shaft 4, and two ends of the transmission shaft 4 are respectively connected with an output shaft of the power takeoff 9 and an input shaft of the oil pump 2 through the universal joints. The oil pump 2 is installed on a longitudinal beam 1 of the frame through an oil pump bracket 3, the oil pump bracket 3 comprises a vertical side plate 31, four bolt holes 35 are formed in the side plate 31 and used for fixing the oil pump bracket 3 on the longitudinal beam 1, the four bolt holes 35 are dispersedly arranged at the corners of the side plate 31, the supporting surface can be increased, and the stability of the oil pump bracket 3 is enhanced due to the large supporting surface; the long round holes 34 are further formed in the side plates 31, positions of rivets on the longitudinal beams are reserved, when the chassis changes, the positions of the rivet holes also change accordingly, the side plates 31 of the oil pump support 3 can be better attached to the chassis longitudinal beams 1 due to the reserved rivet holes, and the stability of the oil pump support 3 can be enhanced. The bottom of curb plate 31 is connected with mounting panel 32, is provided with four screw holes 36 on the mounting panel 32, and the base of oil pump 2 passes through bolted connection with the bottom surface of mounting panel 32, and oil inlet and the oil-out of oil pump 2 are arranged downwards. The mounting plate 32 is located below the side member 1, and the oil pump 2 is located below the mounting plate 32. The input shaft of the oil pump 2 is disposed toward the output shaft of the power take-off 9, and specifically, the mounting plate 32 is shaped in a right trapezoid with the oblique side of the mounting plate 32 toward the outside of the vehicle frame, the side of the mounting plate 32 opposite to the oblique side being connected to the side plate 31, the long side 37 of the mounting plate 32 toward the front end of the vehicle, and the short side 38 of the mounting plate 32 toward the rear end of the vehicle. The structure has the advantages that the oil pump 2 can be closer to the chassis longitudinal beam 1, a sufficient safety gap is reserved between the oil pump 2 and the driving shaft 12 of the vehicle, and the installation angle of the transmission shaft 4 between the power takeoff 9 and the oil pump 2 can be reduced. Since the larger the angle of the propeller shaft 4, the larger the vibration generated, the larger the power consumption, and thus the transmission noise may be caused to damage the oil pump 2. The effectual inclination that has reduced transmission shaft 4 of mounting panel 32 of trapezium structure, the axial of the output shaft of oil pump 2 has certain contained angle with the 1 orientation of longeron of vehicle, and this contained angle makes transmission shaft 4's installation angle reduce, makes the universal joint contained angle at 4 both ends of transmission shaft equal to reduced 4 both ends universal joint clearances of transmission shaft, improved transmission efficiency, prolonged life. The oil pump support 3 has the advantages that the flanges at the two vertical sides of the side plate of the oil pump support 3 are 40mm, the flanges at the long side 37 and the short side 38 of the mounting plate 32 are 20mm, and the rib plate 33 is welded at the joint of the mounting plate 32 and the side plate 31, so that the structure effectively improves the overall rigidity and strength of the oil pump support 3.

An oil inlet of the oil pump 2 is connected with an oil inlet pipe 5, a filter 7 is arranged on the oil inlet pipe 5, a first through ball valve 10 is arranged at the tail end of the oil inlet pipe 5, and the first through ball valve 10 is connected with a first square flange male end interface. In order to avoid the chassis accessories, the oil inlet pipe 5 extends to a small space between the oil tank and the tire along the chassis longitudinal beam 1, extends out of the frame from the lower end of the frame longitudinal beam 1 to the right, extends out upwards after avoiding the chassis steel plate spring seat, then extends out towards the right, and the highest point of the pipeline is noticed not higher than the tractor longitudinal beam 1, because the highest point is positioned in the range of the front turning radius of the tractor, if the highest point is higher than the tractor longitudinal beam, the highest point can interfere with the front suspension part of the tractor when the vehicle turns. An oil outlet of the oil pump 2 is connected with an oil outlet pipe 6, a second straight ball valve 11 is arranged at the tail end of the oil outlet pipe 6, and the second straight ball valve 11 is connected with a second square flange male end connector. The same oil outlet pipe 6 extends to a small section space between an oil tank and a tire along the longitudinal beam 1 in order to avoid the chassis accessory, extends out of the frame from the lower end of the longitudinal beam 1 of the tractor rightwards, extends out upwards after avoiding the steel plate spring seat of the chassis, and notices that the pipeline can not be higher than the longitudinal beam 1 of the chassis. If there is no space for the oil inlet pipe 5 and the oil outlet pipe 6 to be placed outside the chassis longitudinal beam 1, it is considered that the two pipes extend from below the longitudinal beam 1 to a position at the rear of the cab in the vehicle advancing direction, i.e., outside the range of the turning radius of the front of the tractor, and then extend out of the frame from above the longitudinal beam 1. It is worth mentioning that the pipeline system should avoid the oil tank port, the storage battery and other parts as much as possible, and the pumping and filling of the oil tank and the opening of the storage battery cover cannot be influenced. Because the oil pump 2 is hoisted on the longitudinal beam 1 through the oil pump support 3, the oil inlet and the oil outlet of the oil pump 2 are downward, and the lowest point of the pipeline is not the oil discharging port, the oil discharging port 8 is installed on the welding wire seat at the lowest point of the oil inlet pipe 5 and the oil outlet pipe 6 in order to avoid the occurrence of the oil storage condition of the pipeline, and the trafficability of a vehicle is ensured and the wire seat is required to incline to one side during welding in order to ensure the ground clearance of the oil discharging port 8.

s1: the output shaft of the gearbox is connected with a power takeoff 9,

s2: an oil pump bracket 3 is arranged on the frame longitudinal beam 1, an oil pump 2 is hoisted at the bottom of the oil pump bracket 3,
