Description

Technical Field

[0001] This utility model relates to the field of vehicle chassis technology, specifically to a single-engine high-speed vacuum sweeper chassis. Background Technology

[0002] Highways and trunk roads have become the main forms of human transportation and the transport of goods. Various kinds of garbage generated during human transportation will be scattered on the roads. This garbage scattered on the road surface will not only affect the smoothness of traffic, but also cause unnecessary damage to the road surface.

[0003] Due to the high speeds of vehicles on highways and main roads, manual cleaning is no longer in line with the level of modern productivity development. Therefore, sweeper trucks that can meet the daily cleaning and maintenance needs of highways and main roads have become an urgent requirement.

[0004] In recent years, the market demand for high-speed vacuum sweepers has increased significantly, and many manufacturers have successively developed different types of high-speed vacuum sweepers, all claiming operating speeds of up to 60 km / h or even higher. Because users have high requirements for the effective operating speed of high-speed vacuum sweepers, generally requiring 60 km / h, existing high-speed vacuum sweepers all adopt dual-engine power systems. This results in excessively high overall vehicle power, high fuel consumption, high noise levels, and high operating costs.

[0005] The root cause of these problems is that high-speed vacuum sweepers have high power requirements. When traditional commercial vehicle chassis are used as chassis for special-purpose vehicles, the transmission system design lacks scientific rigor and cannot meet the diverse requirements of multiple power systems in special-purpose vehicles. Therefore, a dual-engine power system is the only option, which comes at the cost of excessive power configuration and fuel consumption to meet the different power demands of multiple systems in special-purpose vehicles. Even so, the ideal power matching quality is still not achieved. Utility Model Content

[0006] The purpose of this utility model is to provide a single-engine high-speed vacuum sweeper chassis. Based on a regular truck chassis, it makes full use of the chassis engine power, scientifically improves the power system, and realizes multi-system output and decoupled output of a single power source, thereby meeting the quantity and characteristic requirements of the power system of special vehicles.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a single-engine high-speed vacuum sweeper chassis, comprising a chassis body, an engine and a gearbox, wherein the engine and the gearbox are both mounted on the chassis body, the output end of the engine is connected to the input end of the gearbox, and a full-power power take-off transfer case is installed at the bottom of the chassis body near the middle of the gearbox.

[0008] The full-power power take-off transfer case includes a full-power power take-off transfer case main power input terminal, a full-power power take-off transfer case secondary power input terminal, a full-power power take-off transfer case power output port one, a full-power power take-off transfer case power output port two, a full-power power take-off transfer case power output port three, and a full-power power take-off transfer case power output port four;

[0009] A front drive shaft is installed between the total power input end of the full-power power take-off transfer case and the output end of the gearbox.

[0010] Preferably, mounting brackets are installed on both sides of the full-power power take-off transfer case, and the mounting brackets are riveted or bolted to the chassis body.

[0011] Preferably, a rear drive axle is installed near the rear of the chassis body, and a rear drive shaft is installed between the input end of the rear drive axle and the power output port of the full-power transfer case.

[0012] Preferably, the full-power power take-off transfer case power output port one, full-power power take-off transfer case power output port two, and full-power power take-off transfer case power output port three are used to provide power to the blower, water pump, and oil pump on the sweeper truck.

[0013] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0014] The single-engine high-speed vacuum sweeper chassis provided by this utility model can extract and distribute the full power of the chassis engine (usually greater than the auxiliary engine power of existing dual-engine systems) into no less than four outputs. Moreover, one or more power outputs can be decoupled as needed. Therefore, it fully meets the power requirements of multi-system vacuum sweepers, such as working devices like fans, water pumps, and oil pumps, while maintaining a constant operating speed unaffected by the operating travel speed. The hydraulically decoupled chassis travel power allows for a wider operating travel speed range and higher gear shifting accuracy, transforming from stepped transmission to continuously variable transmission (CVT), and starting from zero for continuous CVT. It can operate at any ultra-low speed, and the power matching quality is better than that of traditional dual-engine power systems. Attached Figure Description

Detailed Implementation

[0024] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0025] The utility model provides Figures 1-6 The single-engine high-speed vacuum sweeper chassis shown includes a chassis body 1, an engine 2 and a gearbox 3. The engine 2 and the gearbox 3 are both mounted on the chassis body 1. The output end of the engine 2 is connected to the input end of the gearbox 3. A full-power power take-off transfer case 5 is installed at the bottom of the chassis body 1, near the middle of the gearbox 3.

[0026] The full-power power take-off transfer case 5 includes a full-power power take-off transfer case main power input terminal 8, a full-power power take-off transfer case secondary power input terminal 14, a full-power power take-off transfer case power output port one 9, a full-power power take-off transfer case power output port two 10, a full-power power take-off transfer case power output port three 11, and a full-power power take-off transfer case power output port four 12;

[0027] A front drive shaft 4 is installed between the total power input end 8 of the full-power power take-off transfer case and the output end of the gearbox 3.

[0028] Furthermore, mounting brackets 13 are installed on both sides of the full-power power take-off transfer case 5, and the mounting brackets 13 are riveted or bolted to the chassis body 1.

[0029] Furthermore, a rear drive axle 7 is installed near the rear of the chassis body 1, and a rear drive shaft 6 is installed between the input end of the rear drive axle 7 and the power output port 412 of the full-power power take-off transfer case.

[0030] Furthermore, the full-power power take-off transfer case power output port 19, full-power power take-off transfer case power output port 20, and full-power power take-off transfer case power output port 31 are used to provide power to the blower, water pump, and oil pump on the sweeper truck.

[0031] Through the above technical solution:

[0032] When in use, when engine 2 is running, all power will be input to full power take-off transfer case 5 through gearbox 3, front drive shaft 4 and full power take-off transfer case total power input terminal 8;

[0033] Through the conversion process of the full-power power take-off transfer case 5, the power will eventually be delivered to the full-power power take-off transfer case power output port 19, the full-power power take-off transfer case power output port 20 and the full-power power take-off transfer case power output port 31.

[0034] The power output ports 1-9, 2-10, and 3-11 of the full-power power take-off transfer case can provide power to the blower, water pump, and oil pump on the sweeper truck.

[0035] In addition, the transfer case power output port 311 can drive the hydraulic pump to change the transmission form. The decoupled power can be re-input into the full power take-off transfer case 5 through the secondary power input port 14 of the full power take-off transfer case, and then transmitted to the rear drive axle 7 through the rear drive shaft 6 to drive the chassis to variable high-speed driving during operation, that is, to realize the single chassis engine to drive the entire power system of the vehicle.

[0036] The single-engine high-speed sweeper chassis of this utility model can perform multi-parameter matching of torque, power, and speed according to the power requirements of each system of the vehicle and the characteristic curve of the chassis engine 2. It can scientifically and rationally match the engine to work near the optimal working point or optimal working range, thereby ensuring that the engine 1 itself is in good operating condition. It can output strong power and has excellent economy, which is one of the important conditions for ensuring the advanced performance of the whole vehicle.

[0037] The single-engine high-speed sweeper chassis can provide the necessary information to the superstructure control system, realize CAN communication between chassis control and superstructure control, and highly integrate superstructure control and power source management according to the construction conditions.

[0038] In summary, the single-engine high-speed vacuum sweeper chassis provided by this utility model can extract and distribute the full power of the chassis engine (usually greater than the auxiliary engine power of existing dual-engine systems) into no fewer than four outputs. Moreover, one or more power outputs can be decoupled as needed. Therefore, it fully meets the power requirements of multi-system vacuum sweepers, such as fans, water pumps, oil pumps, and other operating devices, while maintaining a constant operating speed unaffected by operating travel speed. The hydraulically decoupled chassis travel power allows for a wider operating travel speed range and higher gear shifting accuracy, transforming stepped transmission into continuously variable transmission (CVT), and continuous CVT starting from zero. It can operate at any ultra-low speed, and the power matching quality is better than that of traditional dual-engine power systems.
