Description

TECHNICAL FIELD

[0001] The present application belongs to the field of transmission devices, in particular to a clutch brake. BACKGROUND

[0002] The current transmission system needs to adopt the structure of bidirectional output power in some specific cases, and the structure of bidirectional output power needs to be respectively assembled with independent clutch brake structure when power control is performed. In some transmission systems with rotation or steering function, when the clutch brake is disengaged to disconnect the power of the side transmission system, the relative angle between the half shaft on the power input shaft and the half shaft on the power output shaft will change to a certain extent due to the influence of the inertia condition of the power equipment movement. Therefore, in order to ensure that the clutch brake can smoothly transmit power next time and make the combined power structure run normally, it is necessary to limit the relative angle between the power input shaft and the power output shaft to remain unchanged when the clutch brake is disengaged.

[0003] A left and right steering control mechanism is disclosed in Chinese patent application with application publication number CN110617289A and application publication date December 27, 2019, which comprises a left and right steering lever, a main clutch input gear, a left clutch gear and a right clutch gear sleeved on the left and right steering lever, a left clutch mechanism is arranged between the left clutch gear and the main clutch input gear, a right clutch mechanism is arranged between the right clutch gear and the main clutch input gear, the left clutch gear and the right clutch gear are relatively independent, and the left clutch mechanism and the right clutch mechanism are both toothed clutch mechanisms; a left brake sleeve and a left brake disc, and a right brake sleeve and a right brake disc are further arranged on the left and right steering lever, which are all friction plate clutch brake modes; the toothed clutch mechanism and the friction plate clutch brake are combined to achieve the purpose of controlling the steering of the left and right power output mechanisms, and the structure is simple, the operation is simple and flexible, and the maintenance is convenient.

[0004] When the power input shaft of the above left and right steering control mechanism inputs power to the main clutch input gear, the left clutch gear and the right clutch gear are respectively engaged with the main clutch input gear, the main clutch input gear drives the left clutch gear and the right clutch gear to rotate, and then power is provided to the left power output shaft and the right power output shaft respectively; when steering is needed, taking the control of the left clutch gear as an example, the left clutch yoke is horizontally pulled, the main clutch input gear is disengaged from the left clutch gear, the left brake disc is in friction with the left friction plate in the left brake sleeve, and then the left clutch gear stops rotating, and the corresponding left power output shaft has no power output, while the right clutch gear continues to rotate to drive the right power output shaft to rotate, so that the left wheel connected with the left power output shaft is stationary, the right wheel connected with the right power output shaft rotates, and left steering is achieved. Since the left and right wheel structures are symmetrical, right steering can be achieved conversely.

[0005] But in some specific occasions, the structure of the bidirectional power output only requires intermittent alternating movement between the two power structures without simultaneous movement, and at most only one power structure is in working condition at any time, so the structure of the clutch brake mechanism needs to be further simplified, the structure of the entire power equipment is simpler, and the volume and weight of the power equipment are reduced, and a larger torque is stably output to drive the entire power equipment.

[0033] The present application will be further described in detail below with reference to the embodiments.

[0034] Specific embodiment 1 of the clutch brake provided by the present invention:

[0035] This invention utilizes a clutch mechanism to intermittently control the output shafts on both sides. The moving discs of the two clutch mechanisms move in opposite directions when engaging and disengaging, and the movement directions between the clutch mechanism on one side and the corresponding locking member on the other side are opposite. This ensures that when one clutch mechanism engages, the other clutch mechanism disengages, and the output shaft on the side where the clutch mechanism disengages is effectively braked, so that the clutch can engage smoothly and accurately and output power next time, thus realizing the intermittent alternating output of the two output shafts.

[0036] like Figure 1 and Figure 2 As shown, the clutch brake provided in this embodiment includes a fixed base 6 and a first output shaft 53 and a second output shaft 54 ​​opposed to each other on the fixed base 6. The two output shafts are respectively equipped with input components consisting of a first driven bevel gear 51 and a second driven bevel gear 52, and the two driven bevel gears mesh with the same driving bevel gear 5. The bevel gear transmission effect is smoother and more conducive to transmitting larger torques. A jaw clutch mechanism is provided between the two output shafts and the driven bevel gears. The radial dimension of the jaw clutch structure is smaller, which is more conducive to reducing the size and weight of the brake clutch, and the transmission torque is greater, making it suitable for high-torque transmission systems. The bevel gears are mounted on bearings and are axially positioned by a spacer sleeve 554, an end cover 553, the output shaft, and the first sleeve 551 and the second sleeve 552. The output shaft is axially positioned by the fixed base 6, the right end cover 553, the shaft end nut, the third sleeve 555, and a washer 61. The bevel gear is connected to the output shaft by a spline. When the clutch disc moves into position, it meshes with the bevel gear through the tooth profile, thereby driving the output shaft to rotate.

[0037] The first moving disc 41 and the second moving disc 42 of the dual clutch mechanisms are splinedly mounted on the output shaft and are respectively connected to a swing-type first shift fork 2 and a second shift fork 3. The two shift forks are driven by a drive device, and the swing of the shift forks causes the moving discs to move in opposite directions when engaging and disengaging. A first brake disc 24 and a second brake disc 34 are splinedly connected to both output shafts. A locking element is linked to the shift forks to lock the brake disc on the corresponding clutch mechanism when the clutch mechanism is disengaged, so that the moving disc of one side of the clutch mechanism moves in the opposite direction to the locking element on the same side.

[0038] Only with a set of clutch mechanism to control the power output of both sides, and the brake mechanism and clutch mechanism linkage, using the drive device to drive clutch mechanism and brake mechanism, so that the clutch brake structure is more simple and compact, and make the clutch brake smaller volume, weight, transmission equipment volume and weight also correspondingly reduced, more conducive to the application in some only require two sides of the power structure intermittent alternation of motion without simultaneous movement of the two-way output power mechanism.

The specific structural relationship of the second ejector rod 32, the second connecting rod 31, the second guide hole 33, the second fork 3 and the second brake disc 34 can be known. The ejector rod as the locking member can make the braking operation simple and efficient, the connecting rod hinged between the ejector rod and the driving connecting rod makes the structure simple and compact, and can drive the ejector rod to move and press the brake disc, the transmission effect is stable, and the braking effect is reliable.

[0042] When the hydraulic cylinder is extended, the piston rod pushes the shift fork to rotate around the fixed hinge point, drives the first top rod 22 to move linearly to the right through the first connecting rod 21, and the first output shaft 53 is released from the brake; at the same time, the second connecting rod 31 drives the second top rod 32 to extend, locks the second brake disc 34, and the second output shaft 54 is in the braking state; the shift fork rotates and drives the first fixed disc to move to the left, and is engaged with the first driven bevel gear 51, so that the power is transmitted to the first output shaft 53.
