As one implementation, the brake system 15 includes a brake pipe 151, a three-way joint 152, and a brake 153, wherein the three-way joint 152 is connected to the brake pipe 151, and the brake pipe 151 is connected to the brake 153. The brake system 15 is filled with brake fluid. Brake fluid is transmitted into brake pipe 151 through three-way joint 152, brake pipe 151 transmits brake fluid to each brake 153, and stop or deceleration of traveling assembly 26 is controlled by brakes 153, so that all-terrain vehicle 100 is braked. The three-way joint 152 includes adapter block 1521 and adapter tube 1522, and adapter block 1521 is inside to be equipped with a cavity, and adapter tube 1522 communicates with adapter block 1521. Specifically, the adapter tube 1522 communicates with a chamber inside the adapter block 1521. As an implementation manner, the adapter block 1521 can be installed on the frame main body 121 through a bolt, three adapter tubes 1522 are arranged on the adapter block 1521, and the three adapter tubes 1522 are respectively arranged on different planes of the adapter block 1521 and are basically arranged in a shape like a "T".

Because the number of internal parts of the vehicle body is too many, the brake pipeline 151 needs to transmit brake fluid to different directions, and the brake pipeline is arranged in a bent manner in the prior art, but the turning radius of the brake pipeline is too large, which is not beneficial to the circulation of the brake fluid and the arrangement of the internal space of the vehicle body.

The angle K between the first projection line and the second projection line is greater than or equal to 30 degrees and less than or equal to 150 degrees. Specifically, in the up-down direction of the all-terrain vehicle 100, the projections of the axial lines of two adjacent bending portions 1522a on the first projection plane 304 and the projections of the axial lines of two adjacent adapter tubes 1522 on the first projection plane 304 are substantially coincident, that is, the projections of the axial lines of two adjacent bending portions 1522a on the first projection plane 304 are also the first projection line and the second projection line. Through the arrangement, the bending part 1522a and the adapting pipe 1522 can adapt to the arrangement condition of the brake pipeline 151, and the connection between the bending part 1522a and the brake pipeline 151 is more stable, so that the connection between the adapting pipe 1522 and the brake pipeline 151 is more stable, and the brake fluid is effectively prevented from leaking. In addition, through the setting, the circulation of brake fluid can be smoother, the included angle between the first projection line and the second projection line is selectively set according to the arrangement of the brake pipeline 151, the arrangement of the brake pipeline 151 is easier, and the internal space of the vehicle body is effectively saved.

In this embodiment, the bent portion 1522a is fixed to the straight cylinder portion 1522b and the adapter 1521 by welding, and the straight cylinder portion 1522b is connected to the brake pipe 151 by riveting. The three-way joint 152 in this embodiment can realize the arrangement of the brake pipes 151 in different directions by the design of the bending portion 1522a, thereby providing more choices for the design of the internal space of the all-terrain vehicle 100, significantly improving the circulation efficiency of the brake fluid, and making the circulation of the brake fluid smoother.

As shown in fig. 7-9, the steering assembly 16 includes a steering handle. The braking system 15 includes a handbrake assembly 154. Handbrake assembly 154 is disposed on the handlebar.

The pressure maintaining member 1544 is disposed on the handle 1545, and the pressure maintaining member 1544 can rotate relative to the handle 1545. When the all-terrain vehicle 100 is parked on a slope or the like, and the hand brake assembly 154 is in an unbraked state, the pressure maintaining assembly 1544 is used for braking the all-terrain vehicle 100, so that when the hand brake assembly 154 is in an unbraked state, the hydraulic pressure of brake fluid is maintained through the pressure maintaining assembly 1544, braking of the all-terrain vehicle 100 is further achieved, the all-terrain vehicle 100 is effectively prevented from moving under the conditions of parking on the slope or the like, and the safety of the all-terrain vehicle is improved. The brake switch 1542 is used for quickly lighting a rear brake lamp when the pressure maintaining assembly 1544 brakes, so as to remind a rear vehicle of decelerating, and further improve the safety of the all-terrain vehicle 100. Wherein, the rear stop lamp is a tail lamp that lights up when the all-terrain vehicle 100 is braked. Specifically, the pressure maintaining unit 1544 includes a first state and a second state, the first state being a state when the pressure maintaining unit 1544 is not actuated, and the second state being a state when the pressure maintaining unit 1544 is actuated. Brake switch 1542 is at least capable of transmitting a first signal and a second signal to a rear brake light. The first signal refers to a signal when brake switch 1542 is in a normally closed state, and the second signal refers to a signal when brake switch 1542 is in an open state. When the pressure maintaining assembly 1544 is in the first state, the brake switch 1542 is in a normally closed state, and the brake switch 1542 transmits the first signal to the rear brake light. At this time, the rear stop lamp is not lit. When the pressure maintaining assembly 1544 is in the second state, the brake switch 1542 is in an open state, and the brake switch 1542 transmits the second signal to the rear brake light. At this time, the rear stop lamp is turned on. Through the arrangement, when the pressure maintaining assembly 1544 is in a braking state, the rear brake lamp is controlled to be turned on through the brake switch 1542, so that the rear vehicle is reminded of decelerating, and the safety of the all-terrain vehicle 100 and a driver is improved.

The tank cover 1541a is provided above the tank pad 1541b for sealing the tank 1541, thereby improving the sealability of the tank 1541. The tank pad 1541b is provided below the tank cap 1541a, and the tank pad 1541c is provided below the tank pad 1541b, thereby improving the sealability of the tank 1541. The oil window 1541d is provided at the rear side of the oil tank 1541, so that a driver can check the remaining amount of brake fluid in the oil tank 1541 through the oil window 1541 d.

The return spring 1543b, the piston 1543c, the dust cover 1543d, and the pushrod 1543e are all disposed in the main pump housing 1543 a. One end of the push rod 1543e is connected to the handle 1545, and the other end of the push rod 1543e is connected to one end of the piston 1543 c. The other end of piston 1543c is connected to return spring 1543 b. Specifically, the push rod 1543e penetrates through the dust cover 1543d to be connected with the handle 1545, and the dust cover 1543d can prevent external dust and the like from entering the hand brake pump 1543, so that the brake fluid is kept pure, and the braking effect of the hand brake pump 1543 is improved.

Specifically, the handbrake pump 1543 is provided with a mounting hole 1543 f. One end of the mounting hole 1543f is provided with a push rod 1543e, and the other end of the mounting hole 1543f communicates with the outside of the handbrake pump 1543. Piston 1543c is connected to the one end of return spring 1543b, and the mounting hole 1543f is connected to the other end of return spring 1543b and communicates the outside one end of handbrake pump 1543. In this embodiment, a plug is provided at one end of the mounting hole 1543f communicating with the outside of the handbrake pump 1543. The plug is used to seal the mounting hole 1543f, thereby improving the sealing of the handbrake pump 1543.

In this embodiment, when the hand brake assembly 154 brakes, the handle 1545 drives the push rod 1543e to move, so that the push rod 1543e drives the piston 1543c to move. At this time, the return spring 1543b is compressed, and the handbrake pump 1543 controls the brake fluid to brake the traveling unit 26. When the handbrake assembly 154 is restored to the non-braking state, since the return spring 1543b has a return function, at this time, the return spring 1543b pushes the piston 1543c to move, so that the piston 1543c moves and is returned through the push rod 1543e control handle 1545.

As one implementation, the pressure maintaining assembly 1544 includes a torsion spring 1544a, a pin 1544b, and a park push plate 1544c, as shown in fig. 8 and 9.

The upper push plate, the middle push plate and the lower push plate are integrally formed. The upper push plate, the middle push plate, and the lower push plate form a mounting space 1544 d. The handle 1545 is at least partially disposed in the mounting space 1544d and connects the handle 1545 and the parking push plate 1544c by a pin 1544 b. The pin 1544b is at least partially disposed in the mounting space 1544d for connecting the handle 1545 and the parking push plate 1544 c. Specifically, the pin 1544b passes through the top board, the handle 1545, the torsion spring 1544a and the bottom board, so that the top board is rotatably connected to the handle 1545, and the handle 1545 is rotatably connected to the bottom board. One end of the torsion spring 1544a is connected to the handle 1545, and the other end of the torsion spring 1544a is connected to the down push plate, thereby achieving the connection of the handle 1545 and the parking push plate 1544 c.

In this embodiment, locking teeth 1544e are provided on the side of the parking push plate 1544c that is adjacent to the handbrake pump 1543. One side of the hand brake pump 1543 near the locking teeth 1544e is provided with a clamping portion. When the pressure maintaining assembly 1544 brakes, the clamping portion is clamped with the locking teeth 1544e, so that the parking push plate 1544c is fixed, and the pressure maintaining assembly 1544 maintains a braking state.

Specifically, the braking principle of the pressure maintaining assembly 1544 is as follows: the driver controls the parking push plate 1544c to move through the hand, so that the locking teeth 1544e are clamped with the clamping portion, the locking teeth 1544e are locked with the clamping portion, the pressure maintaining assembly 1544 maintains the braking state, and the pressure maintaining assembly 1544 brakes the all-terrain vehicle 100. When the pressure maintaining assembly 1544 is required to brake the atv 100, the driver controls the locking tooth 1544e to separate from the clamping portion by hand, and the parking push plate 1544c moves towards the handle 1545 under the action of the torsion spring 1544a, so that the pressure maintaining assembly 1544 stops braking the atv 100.

It is understood that the brake switch 1542 is provided with a contact switch. When the pressure maintaining assembly 1544 is not braking, the contact switch is in a normally closed state, and at this time, the brake switch 1542 sends a first signal to the rear brake lamp, and the rear brake lamp is not turned on. When the pressure maintaining assembly 1544 brakes, the parking push plate 1544c drives the locking teeth 1544e to move, the locking teeth 1544e can touch the contact switch, so that the contact switch is in an open state, and at the moment, the brake switch 1542 sends a second signal to the rear brake lamp, and the rear brake lamp is turned on. Through the arrangement, when the pressure maintaining assembly 1544 is in a braking state, the rear brake lamp is controlled to be turned on through the brake switch 1542, so that the rear vehicle is reminded of decelerating, and the safety of the all-terrain vehicle 100 and a driver is improved.
