Abstract
A method and structure for connecting a pneumatic booster (S) to a brake pedal (F) by nesting a second element (3) inside a second element (2) of a control rod (1). The second element (3) is held one inside the first element (2) by a spring clip (25) that is housed in a circular groove (26) of an adapter (5) to define an elastic attachment and allow for play to be taken up to stabilize the connection.
Claims12
A method for mounting a booster (S) in a cabin of a vehicle in which the booster is fixed to a bulkhead (12) separating an engine compartment from the cabin of this vehicle, characterized in that it comprises the following steps:
- a control rod (1) of the booster (S) is made in two portions (2 and 3) intended to be held rigidly one inside the other;
- a first portion (2) of the control rod (1) is engaged in the booster before the booster is secured to the bulkhead;
- and
- a second portion (3) of the control rod (1) is engaged in the first portion (2) of the control rod from the cabin.
A pneumatic brake booster (S) comprising:
- a control rod (1), characterized by a control rod having a first element (2) and a second element (3) that are separable and nested one inside the other with the first element being equipped with a housing to house one end of the second element, said first element (2) is defined by a ball-ended rod (4) that extends from a hollow cylinder section having an inlet cone (9) for accommodating an adapter (5) defined by a overall cylinder member and an elastic device for attaching the second element (3) to the first element (2), said elastic device being defined by a flexible quick-connecting spring clip (25) having a rod bent in two forming a loop and folded at 90° one-third of the way from the formed loop.
A pneumatic brake booster (S) comprising:
- a control rod (1), characterized by a control rod having a first element (2) and a second element (3) that are separable and nested one inside the other with the first element being equipped with a housing to house one end of the second element, said first element (2) being defined by a first portion having a ball-ended rod (4) that extends from a hollow conical section with an inlet cone (9) for accommodating a cylindrical adapter (5) that is hollow with two transverse slots (27), said second element (3) having a cylindrical body with a groove (26) thereon and an attachment device for attaching the first element (2) to the second element (3) by way of the adapter (5) to resisting the pulling-out of the second element (3) from the first element (2), said attachment device being defined by a spring clip (25) that are located in the transverse slots (27) and groove (26) to join the second element (3) to the first element (2).
