Abstract
It the utility model is related to a kind of fork truck master cylinder with oil storage kettle.Including the pump housing, piston assembly is provided with the described pump housing, oil storage kettle is integrated with the pump housing, described oil storage kettle is mutually fixed by connecting joint with the pump housing, and oil storage kettle and the oil duct of piston assembly are communicated with described connecting joint.As shown from the above technical solution, oil storage kettle of the present utility model is integrated by connecting joint, packing ring, O-ring seal and the pump housing, original structure is solved the problems, such as using the external oil can leakage point of oil pipe is more, line loss causes braking response slow, the pump housing uses aluminum alloy material simultaneously, solves the problems, such as that the pump housing gets rusty.Overall structure is simple, and good airproof performance, braking response is fast, and internal leakage is small.
Description
Technical field
It the utility model is related to a kind of fork truck master cylinder with oil storage kettle.
Background technology
Key components and parts of the master cylinder as fork truck, the quality of its braking ability, directly affect the security performance of fork truck.
At present, the master cylinder of domestic and international small tonnage fork car, its pump housing is essentially all cast iron materials, is easily got rusty, and influences its performance.
In addition, master cylinder, by the external oil can of sebific duct, complicated, leakage point is more, and braking response is slow, and cost is high.
Utility model content
The purpose of this utility model is to provide a kind of fork truck master cylinder with oil storage kettle, and the master cylinder is not easy to give birth to
Rust, and without leakage point.
To achieve the above object, the utility model employs following technical scheme：Including the pump housing, it is provided with the described pump housing
Piston assembly, oil storage kettle is integrated with the pump housing, described oil storage kettle is mutually fixed by connecting joint with the pump housing, and described connection connects
Oil storage kettle and the oil duct of piston assembly are communicated with head.
Described oil storage kettle includes oil can body and the oil-can lid with oil can this mates, described oil-can lid are provided with
Dust cover is provided with the ventilation mouth being in communication with the outside and the ventilation mouth.
The oil resistance plug for preventing that fluid from being leaked by ventilation mouth is additionally provided with described oil-can lid.
The bottom of the oil can body is mutually fixed by connecting joint with the pump housing, described connecting joint and oil can body
Packing ring is provided between bottom, O-ring seal is provided between described connecting joint and the pump housing.
The described pump housing is aluminum alloy material.
As shown from the above technical solution, oil storage kettle of the present utility model passes through connecting joint, packing ring, O-ring seal and pump
Body is integrated, solves original structure using the external oil can leakage point of oil pipe is more, line loss causes braking response asking slowly
Topic, while the pump housing uses aluminum alloy material, solves the problems, such as that the pump housing gets rusty.Overall structure is simple, good airproof performance, braking response
It hurry up, internal leakage is small.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
The utility model is described further below in conjunction with the accompanying drawings：
A kind of fork truck master cylinder with oil storage kettle as shown in Figure 1, including the pump housing 1, the pump housing 1 is interior to be provided with piston assembly
2, oil storage kettle 3 is integrated with the pump housing 1, and oil storage kettle 3 is fixed by connecting joint 4 and the phase of the pump housing 1, is communicated with connecting joint 4
Oil storage kettle 3 and the oil duct of piston assembly 2 41.
Further, oil storage kettle 3 includes oil can body 31 and the oil-can lid 32 being engaged with oil can body 31, oil-can lid 32
It is provided with the ventilation mouth 33 being in communication with the outside and is provided with dust cover 34 at the ventilation mouth 33.Ventilation mouth has air-breathing and the work(exhaled
Can, dust cover can prevent extraneous dust from entering oil storage kettle pollution fluid.Being additionally provided with oil-can lid 32 prevents fluid passes through from breathing freely
The oil resistance plugs 35 of the leakage of mouth 33.
Further, the bottom of oil can body 31 is fixed by connecting joint 4 and the phase of the pump housing 1, connecting joint 4 and oil can sheet
Packing ring 5 is provided between the bottom of body 31, O-ring seal 6 is provided between connecting joint 4 and the pump housing 1.I.e. oil storage kettle 3 passes through connection
Joint 4, packing ring 5, O-ring seal 6 and the pump housing 1 are integrated, solve original structure using the external oil can leakage point of oil pipe it is more,
The problem of line loss causes braking response slow.
Further, the pump housing 1 is aluminum alloy material, and using surface hard oxidation technology processing, solves pump
The problem of body 1 gets rusty.
The beneficial effects of the utility model are：1）The pump housing uses aluminum alloy materials, and surface carries out hardening oxidation processing work
Skill technical finesse, it is not easy to get rusty；2）Braking response is fast, builds and presses characteristic good, good airproof performance, and internal leakage is small；3）Integrated level is high, structure
Simply, cost is low.
Embodiment described above is only that preferred embodiment of the present utility model is described, not to this practicality
New scope is defined, and on the premise of the utility model design spirit is not departed from, those of ordinary skill in the art are to this
The various modifications and improvement that the technical scheme of utility model is made, the protection of the utility model claims book determination all should be fallen into
In the range of.
