Description

Technical Field

[0001] This utility model relates to a cooling system device, and more particularly to a cooling system device for a rigid axle off-road vehicle. Background Technology

[0002] Off-road vehicles (ORVs) are high-performance off-road vehicles specifically designed for rugged terrain. Their core features include a body-on-frame construction, a mechanical transfer case (including low-range four-wheel drive and differential locks), front and rear solid axle suspension, and a high-torque engine. To ensure the performance of ORVs, cooling of these high-torque engines is crucial; therefore, the cooling system is an important automotive component. Currently, existing ORV cooling systems primarily use automotive radiators. However, these radiators are limited to cooling only the engine, thus failing to meet the cooling performance requirements of ORVs.

[0003] This invention, through its technical feature of integrating the cooling treatment of the power components of a rigid-axle off-road vehicle into a single system, effectively explores and studies the technical problem of directly using automotive radiators at the technical level.

Its technical purpose is to serve as a component for connecting the oil cooler 4 and the internal radiator 2.

[0081] In this embodiment, the strip portion II 81 is configured as an L-shaped strip with a through hole at the outer end, and the through hole of the strip portion II 81 is configured to be connected to the intermediate connecting bolt located between the outer plate seat 8 and the internal heat sink 2. The seat portion II 82 is configured as a plate with a C-shaped groove on the inner side, and the C-shaped groove of the seat portion II 82 is configured to be connected to the oil cooler 4.

[0082] Its technical purpose is to achieve a clamping connection between the oil cooler 4 and the internal radiator 2.

[0083] In this embodiment, the external radiator 1, internal radiator 2, condenser 3, and oil cooler 4 are arranged in a cooling body composite manner, and the external radiator 1, internal radiator 2, condenser 3, and oil cooler 4 are arranged with shock-absorbing wheel pads 5 and shock-absorbing seat pads 6 in a buffer docking manner. The external radiator 1, internal radiator 2, condenser 3, and oil cooler 4 are arranged with inner plate seats 7 and outer plate seats 8 in an overlapping installation manner. The center lines of the external radiator 1, internal radiator 2, condenser 3, and oil cooler 4 are all on the same straight line. Two shock-absorbing wheel pads 5 and two shock-absorbing seat pads 6 are arranged on the external radiator 1. Four inner plate seats 7 are arranged between the condenser 3 and the internal radiator 2. Six outer plate seats 8 are arranged between the oil coolers 4. Strip plate part II 81 and strip plate part I 71 are respectively arranged to be connected to the support leg column part II 23, and the support leg column part I 22 is arranged to be connected to the ear seat part I 12.

[0084] The method of use in this embodiment is as follows: Place radiator part II 21 onto radiator part I 11, insert the intermediate connecting bolt between the outer radiator 1 and the inner radiator 2 into the through hole of the lug part I 12, and rotate the intermediate connecting bolt between the outer radiator 1 and the inner radiator 2 in the threaded hole of the support column part I 22. This causes the flange of the intermediate connecting bolt between the outer radiator 1 and the inner radiator 2 to act on the outer end face of the lug part I 12. Connect the water outlet port of radiator part I 11 to the water inlet port of radiator part II 21 through a pipe, thereby connecting the inner radiator 2 and the outer radiator 1 together.

[0085] Place the shock absorber seat pad 6 into the mounting holes of the rigid axle off-road vehicle frame. Place the lower end face of the shock absorber wheel pad 5 onto the rigid axle off-road vehicle frame. Place the intermediate connecting bolt between the shock absorber wheel pad 5 and the rigid axle off-road vehicle frame into the intermediate through hole of the shock absorber wheel pad 5 and the mounting hole of the rigid axle off-road vehicle frame. Rotate the intermediate connecting nut on the intermediate connecting bolt between the shock absorber wheel pad 5 and the rigid axle off-road vehicle frame. This causes the flange of the intermediate connecting bolt between the shock absorber wheel pad 5 and the rigid axle off-road vehicle frame to act on the upper end face of the shock absorber wheel pad 5, and causes the inner end face of the intermediate connecting nut to act on the rigid axle off-road vehicle frame. Thus, the external radiator 1 is installed on the rigid axle off-road vehicle frame.

[0086] Place the intermediate connecting bolts located between the inner plate seat 7 and the outer plate seat 8 and the internal radiator 2 into the through holes of the strip plate part II 81 and the strip plate part I 71, respectively. Place the condenser 3 onto the radiator part II 21, with the front end face of the condenser 3 placed on the outer end face of the support column part III 24.

Place the C-shaped groove of the seat part I 72 onto the left and right sides of the condenser 3, and place the C-shaped groove of the seat part II 82 onto the left and right sides of the oil cooler 4. Rotate the intermediate connecting bolts located between the inner plate seat 7 and the outer plate seat 8 and the internal radiator 2 in the threaded hole of the support column part II 23. This causes the outer side of the lower end face of the strip plate part I 71 to act on the outer end face of the support column part II 23, and the flange of the intermediate connecting bolt to act on the outer side of the upper end face of the horizontal body of the plate part II 81. Thus, the condenser 3 and the oil cooler 4 are respectively installed on the internal radiator 2.

[0087] The inlet port of radiator section I11 and the outlet port of radiator section II21 are connected to the heat exchange interface of the engine of the off-road vehicle through pipes. The engine of the off-road vehicle is cooled through the external radiator 1 and the internal radiator 2. The inlet and outlet ports of condenser 3 are connected to the heat exchange interface of the compressor of the off-road vehicle through pipes. The compressor medium of the off-road vehicle is cooled through condenser 3. The inlet and outlet ports of oil cooler 4 are connected to the heat exchange interfaces of the hydraulic system and lubrication system of the off-road vehicle through pipes. The hydraulic oil in the hydraulic system and the lubricant in the lubrication system of the off-road vehicle are cooled through condenser 3.

The second unexpected technical effect was achieved: cooling of the engine of the rigid-axle off-road vehicle was achieved through external radiator 1 and internal radiator 2, increasing the heat dissipation space and improving the cooling effect on the engine. The third unexpected technical effect was achieved: cooling of the compressor of the rigid-axle off-road vehicle was achieved through condenser 3, improving the cooling effect on the compressor fluid. The fourth unexpected technical effect was achieved: cooling of the hydraulic and lubrication systems of the rigid-axle off-road vehicle was achieved through oil cooler 4, improving the cooling effect on the hydraulic fluid and lubricating fluid. The fifth unexpected technical effect was achieved: the shock-absorbing wheel pads 5 and shock-absorbing seat pads 6 were used to mount the external radiator 1 on the chassis of the rigid axle off-road vehicle, preventing external impact forces on the external radiator 1 and improving the stability of the external radiator 1 on the chassis of the rigid axle off-road vehicle. The sixth unexpected technical effect was achieved: the inner panel seat 7 was used to mount the condenser 3 on the internal radiator 2, and the clamping of the seat part I 72 prevented impact forces on the internal radiator 2. The seventh unexpected effect was achieved. Technical effect: The installation of the oil cooler 4 on the internal radiator 2 by the outer plate seat 8 and the clamping of the seat part II 82 prevents the impact force on the internal radiator 2. The eighth unexpected technical effect is achieved: The shock-absorbing wheel pad 5, shock-absorbing seat pad 6, inner plate seat 7 and outer plate seat 8 form a system for the external radiator 1, internal radiator 2, condenser 3 and oil cooler 4, eliminating the impact force between the internal and external parts and extending the service life of the external radiator 1, internal radiator 2, condenser 3 and oil cooler 4.
